KDE Platform Version: 4.4.5 (KDE 4.4.5)

-- Information about the crash:
I had used the "Get tags from Musicbrainz" prior to this crash with no issues. Just prior to this, I had tried to burn the Thor dvd from an iso and got segmentation faults. I was burning another dvd w/o issue when I tried to Get tags... now the problem is constant. As a note, I had libdvdread4 4.1.3-10 when trying Thor but have forced the version back to 4.1.3-8 when installing the dbg files for this crash report. I will restart my system after a few more attempts at Get tags... I will report again if still an issue after restart.

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