since upgrading to 0.10.24 from 0.10.22 (upgrading from ubuntu 9.04 to 9.10)
Pidgin has been crashing when it plays sound through gstreamer. It doesn't
happen every time, but it never happened before I upgraded. I build pidgin from
source so the same version of pidgin was run before and after. I tried
rebuilding pidgin just in case it's binary incompatibility, but it didn't help.
Here's the backtrace:
