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 2.6.31-16-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
The Notifications and Jobs Icon was showing 2 notices.
It showed a title and a job
"1 Jobs finished"  __ X"
"1 file copied       __ X"

I closed the bottom one by clicking the X and it was removed.
I then repeated the same on the title. I have done this before with no issues but this time it crashed the plasma something or other.

the start bar disappeared and then reappeared also the folder view widget moved to it's previous location.
