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 2.6.30.9-90.fc11.i686.PAE i686
Distribution: "Fedora release 11 (Leonidas)"

What I was doing when the application crashed:
After updates KDE has become sluggish. OO takes a lot of time to open, either it could be due to KDE or OO itself. How may I attach top batch log for you.
The taskbar open apps icons become small. Dolphin shows two windows open when only one is opened. The overall feel is buggy.
