Application: kwin (4.7.4 (4.7.4))
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.1.4-030104-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Kwin crashed when I was hoovering over several menu entries in Kmail. This also happens in other KDE programs.
Since I am using the intel driver stack from ubuntus x-swat, the menu entries are not always shown immediately. I have to open a menu point for a second time to see the entries.
Could therefore be an intel driver bug?

The crash can be reproduced some of the time.

-- Backtrace:
