Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-19-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I was logged in normally with my usual compliment of apps running: konsole, firefox, thunderbird, google chrome, x-moto, and google gadgets (gtk).

I wasn't here when the freeze occurred - I was at the store and when I got back my panels were frozen for about 1.5 hours, judging by the (frozen) time on the Digital Clock panel item. Everything else (all the apps listed above) were still running just fine. I closed those manually (except for konsole) and then used xkill to kill the panels. My konsole window was still running on a solid black background so I decided to re-launch chrome and poke around online for an answer. After a while my kde environment started itself back up (with no attempts by me to relaunch) and I was presented with this window.
