Application that crashed: amarok
Version of the application: 2.2.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Running KDE 4.3.2 on Kubuntu 9.10, which I try hard to keep current. Using apt-get update, followed by apt-get upgrade, the system tells me that currently all installed software systems are current. 

Several times in one day, Amarok has crashed after playing from one to a few songs in a playlist of over 600. When Amarok starts-up, a message is briefly displayed saying something about "Falling back to PulseAudio", but the message appears for only a few seconds, so I can't give you the exact wording.

 -- Backtrace:
