-- Information about the crash:
- What I was doing when the application crashed:
After having updated KDE just recently (sinnce it has been updated in debian testing) I see sometimes this kwin krash when doing arbitrary things like browsing in the internet via firefox or checking e-mails in thunderbird.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
