Package: pidgin
Version: 2.10.11-1
Severity: important
Dear Maintainer,
I use Pidgin's IRC feature. Occasionally when the network disconnects, Pidgin
crashes. This bug can be easily reproduced by running Pidgin, signing in an IRC
account, and send the computer to sleep. Pidgin is guaranteed to crash upon
resuming.
I have produced a backtrace, the problem seems to be related an excess free()
call. Below is the backtrace:
*** Error in `/usr/bin/pidgin': free(): invalid pointer: 0x0000555555a0a0e0 ***
