crash (SIGABRT) when cancelling an XMPP file transfer

[pabs3]

I am using Debian stretch, GNOME 3.22, pidgin 2.12.0-1 and GTK+2 2.24.31-2.

Overnight when I was asleep, a friend accidentally initiated an XMPP file transfer, then I got disconnected from that server and in the morning I clicked cancel on the file transfer dialog and pidgin crashed. Pidgin *hadn't* reconnected to the server because this particular one currently has an expired SSL cert so I always have to accept that to connect to it.

I have included the short gdb backtrace below and attached a full backtrace. If these backtraces are not useful, please close the bug.

Program terminated with signal SIGABRT, Aborted.
