plasma-desktop segfaults on startup after kde 4.4.1 upgrade

hi.
after upgrading to kde4.4.1 and restarting (and even rebooting) i experience plasma-desktop segmentation faults. thankfully i am able to start firefox and konsole with Alt-F2.

here’s how my repositories look like:

upgrade path was simple: i just did `zypper up’ and saw that package versions were bumped up to 4.4.1.
