Bug 279152

Application: plasma-overlay (0.0)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
Attempting to reconfigure apps layout since upgrade to KDE 4.7.0., particularly calendar widget. I like the idea of including upcoming holidays, but the calendar has been forced into two panel mode, which is unsightly. Calendar showed full size on widget (full week), however with change, the week is smashed into half the space occupied. Also, the grab handle (??? configure size, position) is missing on all widgets (screensaver mode). The widgets on desktop mode function as they have, with the grab handles popping out when need.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma for the Screensaver (plasma-overlay), signal: Segmentation fault
