Bug 193126

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.86 (KDE 4.2.86 (KDE 4.3 >= 20090514))
Qt Version: 4.5.0
Operating System: Linux 2.6.27-7-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
This crash has been occurring for me with various svn head versions for a month.  It consistently occurs once on kde start, and then plasma restarts and behaves normally.

 -- Backtrace:
Application: Plasma Workspace (kdeinit), signal: Aborted
