Bug 228330

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 2.6.31-19-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
While doing nothing in particular, my plasma workspace suddenly threw a segmentation fault, then reloaded. I suspect from review of Bugzilla that this issue has been solved in a more recent release.

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
