Description Ka-Hing Cheung 2009-09-13 20:58:41 UTC 
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:

Is this reproducible somehow? Could you try if it still happens with gstreamer 0.10.24.2?

In that case it'd be great if you could reproduce it in piding when running inside "G_SLICE=always-malloc valgrind --leak-check=full --track-origins=yes pidgin" and attach the output here.

It's very (but not always) reproducible in 0.10.24.1. Upgrading gstreamer is more involved so I really would like to avoid that. I can try valgrind later today though.

Well, Ubuntu 9.10 should have gstreamer 0.10.24.2 already :)
