[EionRobb]

That's really weird. It looks like it's trying to partially reconnect to the account while the account has been disconnected?

Don't suppose you have any corresponding debug log for this crash? How often does it crash?

[bodqhrohro]

I don't know for sure how this happened. I catched it occasionally while trying to catch backtrace for this issue. Before that, I didn't have any annoying crashes for months. No debug log, sorry.

The steps I made were probably that:

• ran pidgin under gdb;
• left it running for several hours, and didn't notice that skype account disconnected with PPFT error, like it often does;
• manually enabled the account, waited several seconds (not sure if the connection stage had time to complete), then SIGSTOP'ped the pidgin process and suspended the machine;
• next day I resumed the machine, conted pidgin, and after a while got this crash.

Another crash:

I'll do further runs with debug logging to catch some more info.
