Comment 5 for bug 272632

Actually I don't know if I have the exact same trouble, since in my case, pidgin totally freezes.
I have tried what Marquer suggested, but I didn't have the expected output.

Anyway, I ran pidgin in debug mode for some time expecting to find the specific event that triggered the froze; after some time (and a lot of output) I found the following error :

(22:52:27) gstreamer: Failed to connect stream: Invalid argument
