Bug 201929

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.98 (KDE 4.2.98 (KDE 4.3 RC3))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-14-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
reproduction of 201844 (which for some reason did not appear in the bug list here). happened when pressed teh delete button twice when deleting a directory from the desktop plasma. if the delete button is hit twice, i guess the second time get some null parameter and plasma crashes
