Simply uninstalling phonon-vlc 0.2-2010080201.2 (x86_64) solved problem. Leaving it unresolved so that attention is called to this problem.
Hmm, indeed. Fix incoming on git.
Fixed by this commit: Jean-Baptiste Kempf master * r0.2.0-105-gde1a69c /vlc/devicemanager.cpp: Avoid a crash if the vlcinstance wasn't created yet.

Reassigning to the new bugzilla product for better bug tracing of the various backends. Sorry for the noise.

KDE 4.14.6, whenever anything tries to use phonon (system settings, knotify, etc), it crashes with a segfault. Resolved by removing the phonon-vlc plugin. Clearly a regression.
