KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-020635rc6-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
I simply tryied to start the application. I don't know if this hit, but yesterday I updated the system with the new proposed libqt4* updates from:
http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu
Usually the app start with a non-empty playlist.
