[Comment from a bug triager]
I guess that the Phonon backend change crashed some multimedia application (may be Amarok) and that caused the Plasma crash due a different bug.
That bug is fixed in KDE SC 4.6.4 (and may be backported to 4.6.3 by
distributions). The issue was being tracked at bug 258706, merging.
Note that the other crash (Phonon backend change crashing applications) was fixed too.
Thanks
