Qt Version: 4.5.2
Operating System: Linux 2.6.31-18-generic x86_64

What I was doing when the application crashed:
i tried everything i could think of - purging amarok, reinstalling phonon/xine, copying files from the test-user. but no matter what i do, amarok only starts with the test-user.

Comment 1 Johannes M. Wagner 2010-01-19 01:51:03 UTC

looks like i found a workaround: 

- make sure to completely remove pulseaudio from your system, if present
- delete all phonon- and amarok-configuration-files (maybe you can skip this)
- delete the $HOME/.xine directory

after that, amarok should startup again quite fine.

i experienced that bug several times by now - some app depends on some sound-plugins i dont really want, the bug up my system, mostly pulseaudio involved, and amarok, dragonplayer and other apps depending on phonon stop to work properly.
only removing those packages und resetting the xine-cache solves that problem.

i found so many people experiencing the same problems as me, so i hope, this workaround will help some of you! for the amarok developers: it doesnt seems to me to be an amarok-bug, but maybe you could tell the xine-guys to fix that, because amarok is heavily inflicted?

Comment 2 Myriam Schweingruber 2010-01-19 10:00:37 UTC

Well, you are not supposed to use Pulseaudio when you use Kubuntu and KDE only, since Pulseaudio is only needed for Gnome. 
This is not an Amarok bug, but a distro specific one, not much we can do about, sorry.
FWIW, the bug is a duplicate of bug 188602

removing ~/.xine/catalog.cache works for me, thanks!
