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:

I tried different revisions between 0.6.4 and 0.6.5 and the first one that freezes is rev. 1222:
http://bazaar.launchpad.net/~listen-devel/listen/devel/revision/1222

If I break into listen with gdb after freeze I can see that listen is stuck inside xcb_wait_for_reply

So this can be actually a bug in libxcb.so.1.1.0.

Listen freeze after that :

/usr/lib/listen/plugins/source/lastfm_information.py:262: GtkWarning: IA__gtk_progress_set_percentage: assertion `percentage >= 0 && percentage <= 1.0' failed
  progress.set_fraction(frac)

[Martin Erpicum (martin-erpicum)]

I upgraded Listen to the last version available in the listen-devel ppa. It don't freeze anymore.

Maverick 10.10
computer ~ $ listen --version
** Message: pygobject_register_sinkfunc is deprecated (GstObject)
listen 0.6.5.99~bzr1305

[Marcin Grześkowiak (mgrzeskowiak)]

listen 0.6.5.99~bzr1305 still freezes for me, although it works a bit longer than 0.6.5
it freezes for me also without assertion from IA__gtk_progress_set_percentage
what I always see in the output is warning from fadebin saying that a stream is already blocked, e.g.:
