Comment 1 Myriam Schweingruber 2012-04-22 09:04:17 UTC 
The bug is in the phonon-backend-gstreamer, already solved in the upcoming version 4.6.1

*** This bug has been marked as a duplicate of bug 288305 ***
Comment 2 Mathias Panzenböck 2012-04-22 14:27:20 UTC 
Great! When will 4.6.1 be released (approximately)? (I guess you have no idea whether it will be included in an update to Fedora 16?)
Comment 3 Myriam Schweingruber 2012-04-22 15:46:40 UTC 
No idea, I guess the best is to actually ask in #kde-multimedia on irc.freenode.net.
