Comment 1 Andrea Diamantini 2011-12-29 17:51:36 UTC 
This crash is Phonon/GStreamer related, here is because amarok (using phonon as media library) and rekonq (with webkit using phonon) crashed.
Comment 2 Myriam Schweingruber 2012-07-30 20:39:12 UTC 
Is this still valid with version 4.6.1 of phonon-backend-gstreamer?
Comment 3 Myriam Schweingruber 2013-04-13 11:40:34 UTC 
Closing for lack of feedback. Please feel free to reopen if this is reproducible with the phonon-backend-gstreamer 4.6.3 or later.
