The current package 0.9~beta10+svn1073-0ubuntu1 still freezes at times
on my system. The freeze occurs whenever the playlist reaches the end
of an album (not necessarily the end of a playlist).
To trigger the bug:
1. Add any two albums to the playlist from the Music Store in "Album" mode
2. Start
Kubuntu 9.10
Check your Xorg log for complaints about GLX. In my case a package
update removed the symbolic link from libglx.so to libglx.so.185.18.36
in /usr/lib/xorg/modules/extensions. Restoring this link fixed the
problem.
