A crash that shoudln't have happened

When I re-joined a group chat:

Thread 1 "pidgin" received signal SIGSEGV, Segmentation fault.

What does that IRC account do here? It wasn't even enabled for months (or even years, as I dropped using the Pidgin's buggy IRC prpl a long time ago). Looks like a severe memory corruption issue, maybe not even in the telegram-purple itself.

Side note: Since telegram-purple does some weird memory-overflowy things, I wouldn't be too surprised if it turns out that this is due to telegram-purple afterall.

@bodqhrohro what version of pidgin are you using?

[bodqhrohro]

@EionRobb Pidgin 2.14.1 (libpurple 2.14.1)
