I've attached a small 'C' file that reproduces the same crash if it is run = after emacs has copied some text to the kill ring. It seems to have started happening after git commit be35c92c90d455739a6ff9d= 4beefa2b35d044852.

The bug doesn't seem to happen when running under Wayland.

To reproduce:-
1) Have xfreerdp (RDP client) running and connected to a remote system= .
2) Run emacs on the same system as xfreerdp.
3) Copy some text to the kill ring.
4) Emacs crashes with an error.

(emacs:241123): Gdk-ERROR **: 14:26:18.002: The program 'emacs' receiv= ed an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.

I dug into this a bit and what seems to happen is emacs calls gdk_x11_= window_change_property twice for the same window.

gdk_property_change (window=3D0x555556648a50, property=3D0xb2, type=3D= 0x4, format=3D32, mode=3DGDK_PROP_MODE_APPEND, data=3D0x5555564bc510 "= \260", nelements=3D26)
gdk_property_change (window=3D0x555556648a50, property=3D0xb2, type=3D= 0x46, format=3D8, mode=3DGDK_PROP_MODE_APPEND, data=3D0x555556032498 "= Emacs", nelements=3D5)

once to set a list of atoms and again to set a utf8 string. freerdp do= esn't delete the property in between and this causes the X error because th= e data type doesn't match when using GDK_PROP_MODE_APPEND.

I've attached a small 'C' file that reproduces the same crash if it is= run after emacs has copied some text to the kill ring.

It seems to have started happening after git commit be35c92c90d455739a= 6ff9d4beefa2b35d044852.

This crash is known to happen there, and will not be fixed, since adding 300-400 lines of X specific selection code to the PGTK port seems very irrational for a platform that it is not intended to support.

The segfault (which is really not a segfault, just GDK displaying a window system error and aborting in an unusual manner) is hard to avoid without adding X specific error handling code (gdk_x11_display_error_trap_push). Which will then add a dependency on the X11-specific parts of GDK, and won't work if Emacs did not see them at build-time.

Surely there's something Emacs can do here -- it doesn't have to do something sensible, it just has to not abort.

GDK doesn't have a generic "window system error" concept, which is only present on X11. So unless you write error trapping code specific to X11, there's no way to handle those errors. And doing that isn't reliable if the GDK X11 development files were not installed at build-time.
