[Octave-bug-tracker] [bug #65312] "__run_test_suite__" ran in GUI hangs Octave in some configurations

[John W. Eaton]

Follow-up Comment #14, bug#65312 (group octave):

"journalctl | grep -i glib" shows nothing on my system.

When I was first trying to debug the hangs, I attached gdb to teh Octave
process and saw that it was often in this state:

The file it appears to be looking for doesn't exist on my system.  I don't
know why it would hang there, if it was.  But that traceback showed up
repeatedly and it seems unlikely that I would randomly catch it there multiple
times if it wasn't stuck or waiting for something.
