Re: gmc problem with window manager delete even

[Lyndon Drake <lyndon stat auckland ac nz>]

Hi,

Something I should have noticed before is that gmc only crashes the first
time I run it in a particular X session.  Note that this appears to be
unrelated to gnome-session.  I tried just running E (with nothing else):
the first time I started gmc it crashed when I clicked the close button,
and from then on it ran without problems.  The same behaviour is repeatable
when running gnome-session: my Gnome session comes up, I open a gmc window,
click the close button, and gmc crashes.  In this case, the session manager
respawns gmc, and from then on it works perfectly.

I finally worked out that plain-gmc is the "real" gmc, so I ran it under
gdb and got the following backtrace.  Note that my original report said
that it segfaulted, whereas in fact it got a SIGABRT.
