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 2.6.31-14-generic-pae i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
System Kubuntu release 9.10 Karmic Koala
KDE version 4.3.2
plasma-widget-fancytask 0.9.8

Plasma crashes when closing some aplications.
After closing sometimes the icon is still on the fancytasks applet.
