Subject: msn-pecan: SegFault on msn_message_destroy
Date: Mon, 11 May 2009 12:10:03 -0300

Package: msn-pecan
Version: 0.0.18-1
Severity: important


I've not been able to find the exact cause for this issue to happen but every now and then pidgin would just crash. I 
installed pidgin-dbg and got the following backtrace:

(gdb) handle SIGPIPE noprint nostop
Signal        Stop	Print	Pass to program	Description
SIGPIPE       No	No	Yes		Broken pipe
(gdb) run

I'll see about installing debug symbols for this package too and update this
