Comment 8 Myriam Schweingruber 2012-09-14 13:23:16 UTC 
Is this still valid with Amarok 2.6.0 or current git? There have been quite some changes in the media devices code since 2.4-git
Comment 9 Myriam Schweingruber 2012-10-21 09:26:17 UTC 
Closing for lack of feedback. Please feel free to reopen this report if you can reproduce this with current Amarok 2.6 and provide a new backtrace.
