Bug 289577

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
В том-то и дело что ничего не делаю. Рабочий стол в покое и тут бац!...плазма креш. Таскбар пропадает. После перезагрузки повторяется тоже самое через какой-то промежуток времени.
Мне пофигу если там никто из вас не понимает русского. Я готов плакать и прокленать линукс. Ни дня покоя. Каждый день какие-то глюки. А после перехода на 11.10 я проклял линукс как ОС в течении 15 минут. Спасите ВАШИ души от пекла! Исправте ошибки!

The crash can be reproduced every time.

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