+++ This bug was initially created as a clone of Bug #320855 +++

Application: amarok (2.7-git)
KDE Platform Version: 4.10.60 "release 10"
Qt Version: 4.8.5
Operating System: Linux 3.10.0-rc4-1.gb3d0118-desktop x86_64
Distribution: "openSUSE 13.1 Milestone 1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

*Probably* caused by fe61ba48d5bb86222684919fd27f339d0e7a1013 in kdelibs... as the bt shows it crashes in Plasma::Theme.
There is also a soprano/virtuoso related crash ...

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault

I wrote a patch for bug #320855, but I couldn't reopen the other bug, so I'm cloning. I'm sorry if this is the wrong way to push it forward.
