Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1
Operating System: Linux 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
I had just updated my KDE system in the morning. After the updates I have found that the Glassified theme for plasma doesn't look right: if I was moving the pointer towards any widget, there was no buttons on the menu slider (resize, widget settings, close widget etc) and there were no icons at the PyWeather widget. 
I closed the widget and added it again wich caused the crash.

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