This problem is also affecting me with a fresh, clean install of Ubuntu 9.10 on a Dell 4600.

I first inserted an audio CD and I got an error saying something about sound-juicer not being there.  I tried opening brasero to make a backup of an audio CD and it would open up the program, then suddenly crash.  Same thing happened when I tried Rythmbox Music Player or just opening with Nautilus.

I installed sound-juicer and now when I insert an audio CD, it started to play the CD and kept playing, but sound-juicer crashed.

I enabled Apport, it autogenerated a report which I associated with the bug number (501207).  Here is what was in my /var/log/messages for my various attempts:
