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 2.6.28-13-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I'd just restarted X and KDE, and while the system tray was still loading services, Kwallet asked for my password (presumably for the OpenSocial desktop widget - my only widget with a folderview desktop). I entered the password and immediately clicked on the "Nearby" tab. Plasma crashed immediately.

TECH SPECS:

KDE 4.3 beta 2
Kubuntu Jaunty AMD 64 (Phenom II quad core)
ATI HD4850 + fglrx 9.4
4 Gig ram
