Subject: GIMP startup crash on minimal xorg/wm unless gtk+ in profile
Date: Wed, 21 May 2025 15:34:39 +0000

Hello Guix,

I've noticed that the new Gimp version 3.0.0 crashed on startup for me.
The error message is:

(gimp:5025): GLib-GIO-ERROR **: 22:39:28.588: Settings schema 'org.gtk.Settings.FileChooser' is not installed
/gnu/store/vk8xddd7cr2dcsqjwvvyrhidg1brdsaq-gimp-3.0.0/lib/gimp/3.0/plug-ins/script-fu/script-fu: fatal error: GIMP crashed
Trace/breakpoint trap

Or a variant thereof.

This probably happens because my GUI is a relatively minimal Xorg + dwm.
If I install the package gtk+ onto my home profile, then Gimp 3.0.0
starts, and its file chooser apparently works.

Anyway, I don't want to have dbus in my profile anymore, and although
I've seen on the news that Gimp is now a full-blown Gtk app, it *still*
does not seem to want to play completely nice with my window
manager. Well, that is to say, its main window doesn't tile. So, I put
my foot down, no Gimp for Runciter in the near future.

Still, it occurs to me that gtk+ should probably be a propagated
input of gimp-3. Some Package(s) which probably have a similar run-time
dependency situation seem to proceed like this; such as zathura having a
propagated input to girara having a propagated input to gtk+.

I'm going to submit a patch, in case it is helpful.

Regards,
Runciter

Wrapping the gimp binary should be preferred.  I think it already is but
maybe something is missing?

I've been looking at the package for nyxt which also has gtk-esque
inputs, I think maybe (just maybe), gimp needs to be started with
LD_LIBRARY_PATH pointing to the lib directory of the
gsettings-desktop-schema package in its environment.

I'll see when I have time to try this, if someone wants to have a go
don't hesitate.

Maxim, you marked #78667 as a duplicate of this bug. It's possible also
#78667 and this bug are duplicates of #78075.

Hi Guix!

It wasn't LD_LIBRARY_PATH that needed wrapping finally, it was
XDG_DATA_DIRS.

I just submitted a revised patch.

When I think about this, after this patch, considering the case of
people who have both gtk+ and gimp in their profile, the variable
XDG_DATA_DIRS in the environment of a running gimp should be clobbered
or quasi-clobbered, however you want to call it. Although this should
generally not result in failures, it seems it has in the case of another
variable, bug#77921. I don't think it should be always preferred to use
'=' instead of 'prefix' for wrapping, though. If there's a cleaner way
to do this, let me know.

Regards,

I think prefix should work, even for the case referenced in #77921. I
had used = to be extra careful, but prefix is probably better if it
works.

If you are able to test it, you may want to standardize all wrapping in
gimp to use prefix.

It's done, all wrappings now use prefix. I just submitted a revised
patch v3.

I have tested that gimp starts successfully with and without gtk+ in the
user profile.

While this is v3 of the patch, I have just realized that my global git
configuration was preventing the Change-Id from showing up at the end of
commit messages. As a result the first and v2 patches did not have a
Change-Id.

Are you able to run it this way?

--8<---------------cut here---------------start------------->8---
./pre-inst-env guix shell --pure gimp -- gimp
--8<---------------cut here---------------end--------------->8---

For me it still fails to run, apparently it fails to load its PNG icons.
Maybe it also needs to be wrapped with GDK_PIXBUF_MODULE_FILE ?

I hadn't tried and yes, it still fails to run in the pure environment.

I tried the obvious way of wrapping with GDK_PIXBUF_MODULE_FILE, gimp
was still unable to load its icons. I probably did it correctly because
I saw the value as expected in the wrapper script.

There's still something in my user profile that's helping gimp to start,
now it's not gtk+ anymore; this can be investigated. If that devolves
into a slow process of elimination, I'll be able to do that next week.

Some progress!

I found that it currently needs the package gegl in the profile
understand the png format.

./pre-inst-env guix shell --pure gimp gegl -- gimp

This successfully showed the splash screen before crashing.

I'm on business trip and there's no hope that that my X60 will compile
guix, so I'm stuck testing the gimp package using 'ssh -Y' to back home,
until Sunday. So it will be helpful if someone can just confirm that
GIMP does crash after showing its splash screen with my latest patch +
gegl in the pure profile.

With gegl in the pure profile, it understands the png format, but it
still fails to recognize the svg format of at least one picture; this
probably relates to the package dependency structure, gimp depends on
libpng through its gegl input.

So... No revised patch and I guess I won't be able to make progress in
the near future. I'm kind of at the end of my wits with this, and
definitely lacking knowledge about gtk. Here's where I'm at:

After applying my patch V3, that is to say wrapping the data files
directory of the gtk+ package into XDG_DATA_DIRS, you can get GIMP to
complete startup in a more minimal profile; most minimally, it can be
obtained with the following command:

./pre-inst-env guix shell --pure gimp gdk-pixbuf -- gimp

gdk-pixbuf pulls glib in its propagated inputs. Trials showed that gimp
needs glib in the profile in order to load PNG icons, and it also needs
gdk-pixbuf in the profile in order to load SVG icons.

Yet, trying your suggestion of wrapping GDK_PIBUF_MODULE_FILE has been
unsuccessful, both for SVG and PNG icons.

Creating a propagated input or a chain of propagated inputs from gimp to
gdk-pixbuf while applying the path V3 and leaving gtk+ out of the
propagated inputs of gimp should work, if that's acceptable.

Interesting!  As perhaps one last thing to check, you could compare the
environment variables set in that profile, or compare the output of
'strace -e file -f -s200 gimp' when it works and doesn't.

Thanks for the advice Maxim, that did open new pathways for trial and
error.

I just submitted a patch version 4 which has gimp succeed at starting
without crashing in a pure shell.

Finally, it is very much necessary to export GDK_PIXBUF_MODULE_FILE from
the wrapper script, as you suggested. I must have missed it originally
because it is also imperative that gimp sees the data files of the
shared-mime-info package.

Yay! Very good that you persevered on that one, that's a happy
resolution!

I'll look into trying and pushing your patch when I have a chance.

Well done!

XDG_DATA_DIRS need not be duplicated, and references to packages should
be done via this-package-input/this-package-native-input or
search-input-file rather than ungexp directly, as this would make
rewriting inputs impossible:

I've followed-up with a couple additions, such as libjxl support.
