retitle 34454 Gtk upstream bug #1280 causes crashes in IceCat and Emacs
thanks

Hello all,

I looked into this, and I believe all of these bugs are caused by Gtk
upstream bug #1280:

  https://gitlab.gnome.org/GNOME/gtk/issues/1280

which is apparently fixed by the following upstream commit:

  https://gitlab.gnome.org/GNOME/gtk/commit/e3a1593a0984cc0156ec1892a46af8f256a64878

Here's another upstream bug report that's more obviously related to
this, and upstream decided it was a duplicate with #1280:

  https://gitlab.gnome.org/GNOME/gtk/issues/1523

Also, here's the same bug reported for NixOS and Arch:

  https://github.com/NixOS/nixpkgs/issues/53697
  https://bugs.archlinux.org/task/61050

I've attached a proposed patch to fix this in Guix.  I'm currently
testing the patch on my system to make sure it doesn't cause any
problems, although I cannot reproduce this bug on my own system.

If those affected by this issue would like to test this patch and report
back, that would be helpful.

     Regards,
       Mark
