Bug 294089

Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.00 (4.8.0
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic-pae i686
Distribution: Ubuntu 11.10

-- Information about the crash:
Při změně úsporného režimu dojde k restartu plochy KDE (režim pohled na složku). V panelu se zvětší velikost informačního widgetu - posune se velikostně zleva doprava, asi do poloviny panelu. Tím se zmenší místo pro minimalizovaná okna.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Shell plochy Plasma (plasma-desktop), signal: Segmentation fault
