Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-17-generic-pae i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
When this widget is placed on the panel is an icon of your home directory. When the widget is placed on the desktop it shows all the folders in your home folder. When I moved it from the panel to the desktop it showed both at first. Then I tried to increase the size of the widget ( in order to let it show more directory icons ) it suddenly crashed.
