Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-11-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
The first time I zoom out of an activity then in again plasma crashes.  Subsequent zooms do no cause crashes.  On the first zoom out the plasma menu is not visible, after the crash it is.

 -- Backtrace:
