Comment:
since python-gst (the 0.8 version) is a Depends of ubuntu-desktop, this
is a fairly serious problem. The latest dapper update reinstalled
ubuntu-desktop and reintroduced this problem to me.

I also tried to open a different playlist and got the following traceback (via serpentine -n 2> serpentineerror.txt)
