[GnomeMeeting-devel-list] GM 1.3 segfault

[Peter Robinson <pbrobinson gmail com>]

Hi All,

I have two accounts configured in GM 1.3. One is a sip provider and
the other is the H323 phone system we have at work. Normally I run GM
with the H323 one disabled and the SIP one enabled as I haven't
actually had time to play properly with the work phone system. Today I
decided to play so bought up the GM account preferences disabled the
SIP account, enabled the H323 account hit OK and wammo GM died. I
restarted it and it didn't reappear so ran it up through gdb and got
the following backtrace with the debuginfo packages installed for
peoples debugging goodness. Let me know if you need more info.

Cheers,
Pete
