Thanks.  What this says is that GDK has emitted an event, which is being
dispatched to what it thinks is a widget, but either the widget's signal
handler or the widget itself is invalid, causing GObject to crash during
signal dispatch.

Would you please install debuginfo for libgdk-3.so.0, libgtk-3.so.0 and
libgobject-2.0.so.0 (I'm not sure how to this in the GuixSD) and try to
figure out what event is causing the crash?

I suggest going up to frame #12 and typing:

  (gdb) p *event

after the debuginfo is installed and loaded by GDB.
