First of all thanks a lot for keeping the pidgin package updated.
Try remove your gstreamer folder from your home directory....
I tried that one before, but it didn't help.
Tried with this version again, but I still get the same error.
I have gst-plugins-good and gst-plugins-bad installed,absence of which was causing this problem for the people at arch linux forum
Does this function work for you?
I think I found what the problem was - I didn't have gst-plugins-farsight installed.
Now it just says "Error creating session."
Actually no, I tried again, pidgin crashed, and now it's back to the whole valve element business again.
