Application: plasma-desktop (0.3)
KDE Platform Version: 4.3.95 (KDE 4.3.95 (KDE 4.4 RC2))

Operating System: Linux 2.6.33-020633rc4-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
KDE 4.3.95 from Kubuntu ppas.

Whenever I try to add a widget to my tray, plasma crashes. Bubblemon seems to be an exception of sorts; it gets added and flashes there visually for a bit, but then disappears. The other widgets (Device Notifier, Paste, Battery Monitor, Weather Forecast) just crashes it consistently. Widgets are unlocked.

The crash can be reproduced every time.
