Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.4 (KDE 4.4.4) "release 3"
Qt Version: 4.7.4
Operating System: Linux 2.6.34.10-0.2-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
Opensuse 11.3 x86-64 aftwer upgrading to current qt 4.7.4-221 from opensuse repositories here :
http://download.opensuse.org/repositories/KDE:/Qt/openSUSE_11.3
plasma crashes systematically after login.
Restarting plasma manually yields the same result ->crash - so the desktop is unusable.

Starting the plasma--desltop application from command line shows:
