Arch Linux

Description:
Everytime I start amarok it crashes and DrKonqi (KDE's bug reporter) openes and shows me and not usefull stacktrace.

I tried the official amarok package, the amarok-git package and an self-built git clone. All produce the same error. I build the last one with debugging symbols, and here is the output of gdb:

I tried deleting all amarok config files I found but it didn't help.
