Hi guix,

Here is a backtrace from mumi.log.zst and mumi.mailer.log.zst.
This lead to a 500.

When playing with the Guile interface of Mailutils, I remember you had
to define that variable because ‘mu-message-send’ would look it up in
the current module (argh!):

  ;; This variable is looked up by 'mu-message-send', uh!
  (define-public mu-debug 0)

So I guess you can try adding this snippet in the module that uses
‘mu-message-send’ (?).

HTH!

‘the current module’ is whatever (current-module) evaluates to.
It is not necessarily the module wherein 'mu-message-send' is used.
IIUC, every time a (define-module ([...])) form is encountered,
(current-module) is set to [...], or something like that (details
might be a little different).  It works for stand-alone scripts and
in the REPL I guess, but otherwise it's a very cumbersome interface.

This interface should be changed (in mailutils) IMO.

nckx has done that recently.  Pages on <https://issues.guix.gnu.org/NNN>
now end with ‘Commenting via the web interface is currently disabled.’.

I pushed a patch to fix this in Mailutils in commit
a5fb1f4eeb7563bd8519660c452a45afecd296c6, and also submitted it
upstream.

I guess we could try re-enabling the comments via the Web interface of
mumi?

Thanks,
Ludo’.

Since this feature has been broken repeatedly with nefarious
consequences (silently disappears user reported issues!), I think we
should come up with a test for it, if we want to re-enable it, so that
we can ensure it keeps working in the future.
