Comment 1 for bug 580586

I started experiencing this after upgrading to Xubuntu 10.10 (python 2.6.6) with Listen 0.6.5. It was ok on Xubuntu 10.04 (I don't remember exact version of Listen, but I used the one from Ubuntu repositories).
I just open Listen, start playing a song, then switch to another song and maybe another one. UI stops refreshing and it does not react to mouse actions (the same with panel applet). The last selected song plays until the end.
One time Listen somehow managed to freeze the whole desktop - I had to switch to console and kill Listen to be able to do anything with Xfce.
Things I can see in the terminal:
