--------------------------+-------------------------------------------------
 I have Pidgin 2.2.1 running all day long (of course!). Sometimes, while
 not doing anything at all with it, it will crash out of the blue. I got
 the following backtrace:

 #0  0x28d4d537 in pthread_testcancel () from /lib/libpthread.so.2

 I also frequently get warnings such as the following (which makes me think
 that somebody is not clearing some allocated memory before using it). This
 seems to be gstreamer related.

 (pidgin:84006): GStreamer-CRITICAL **:
 Trying to dispose element fakesink, but it is not in the NULL state.
 You need to explicitly set elements to the NULL state before
 dropping the final reference, to allow them to clean up.

 Again, this seems to be gstreamer related where something is released that
 is either not ready to be released yet or has already been released (or
 something like that).

 Hope this helps at all,
 Sven
