Gaim has segfaulted and attempted to dump a core file.
This is a bug in the software and has happened through
no fault of your own.

It is possible that this bug is already fixed in CVS.

Please make sure to specify what you were doing at the time,
and post the backtrace from the core file. If you do not know
