[gutsy] segfault in IA__g_type_check_is_value_type

[Brian J. Murrell]

Binary package hint: gnome-panel

For some reason, in gutsy, apport is not catching this failure, but gdb on gnome-panel before it crashes and then getting a backtrace when it's crashed shows:

Program received signal SIGSEGV, Segmentation fault.

I'd love to send an apport report instead as I'm sure it would be infinitely more useful, but they are just not happening here for whatever reason.

Apport has not yet been turned on for Gutsy as we are currently working on some infrastructure changes to allow for duplicate detection etc.

Yeah, so I had discovered a few weeks ago, but I asked how and turned it
on. It seems to be creating 0 byte files in /var/crash though. Guess
maybe it's still in a state of flux.

Wow. This one is a PITA! It's crashing every few minutes and restarts
(as the gnome-panel does when it crashes) and crashes and starts, and so
on and so on.

Some love here would be appreciated. :-)
