Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.81 (KDE 4.4.81 (KDE 4.5 >= 20100527)) "release 8"
Qt Version: 4.6.3
Operating System: Linux 2.6.31.12-0.2-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: I had just finished upgrading to KDE 4.4.8, installing nvidia drivers to run 3 monitors, which I finally succeeded in doing. and notiiced that my desktop panel disappeared from the upper left corner.. I like that feature and use to put in my most-used apps. It's cool. Thanks.
