Pidgin crashes when a message sent

[Sesivany]

Sometimes (not very often, once in a few days) when I send a message, Pidgin crashes. The message still gets sent, so Pidgin crashes right after that. I haven't found any pattern what kind of message can trigger that. The backtrace is:

I can also provide a codedump if necessary (it has >200MB).
I'm using Pidgin 2.10.11 and telegram-purple beta 3 in Fedora 22.

[majn]

Sending the core dump won't be necessary, but can you please try to get some additional inform from the coredump?

dnf install pidgin-debuginfo

gdb pidgin ./coredump
run
bt full

Then try to find the frame number of "tglq_query_result" and print the local variables.

frame <frame-number-of-tglq_query_result>
info locals

If that doens't work, please just the full backtrace.

Here is a crash report in ABRT: https://retrace.fedoraproject.org/faf/reports/726722/ Apparently, I was experiencing the crash already a month ago, so it's not something new introduced with beta 3.

This crashing on outgoing messages was already fixed in a hotfix for 1.2.2, closing now to clean up.
