Are you sure, that your Pidgin is built with this patch applied? I'm
pretty sure, that pointed revision *fixes* the problem (I had exactly
the same backtrace before writing it).

And here is the patch, which broken this for me:
http://hg.pidgin.im/pidgin/main/rev/f7b7a6c58ad3 (both are in
release-2.x.y, but not in 2.10.6).
