[Nix-dev] (kde 4.8): knofity4 PID: 21830 Signal: Segmentation fault (11)

some news about this issue:

shows the same messages as described in [1]. i then used 
'systemsettings' - 'application and system notifications' - tab 'player 
settings' and there i set it to 'no audio output'. right now that is the 
best solution for me.

it seems that the audio backend of kde is not configured properly -> in 
systemsettings i get this messages (when started from a shell) when 
accessing: multimedia - phonon

systemsettings(18396)/kdecore (KLibrary) findLibraryInternal: plugins 
should not have a 'lib' prefix: "libaudiocd_encoder_lame.so"

still dragonplayer and most other kde using applications (which use 
phonon) will crash. still searching for an solution.
