Comment 1 Alejandro Nova 2011-05-11 05:56:48 UTC 
Please, install all the relevant debug packages and test again. This might have been fixed with Amarok 2.4.1 or Phonon-GStreamer 4.5.1.
Comment 2 Kevin Funk 2011-05-11 14:35:57 UTC 
@Alejandro: Sorry, but that is not correct. The crash happens inside Webcore (see thread with KCrashHandler line).

Likely a duplicate.
