Bug 275183

Application: kwin (4.6.2 (4.6.2))
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed: I had Virtual Box open, running hacked ver. of Vista w/ guest additions. I am using the Neon Fruit theme with buttons, I grab the window border to minimize window and kwin crashed. I have 4gb ram, and dedicated 775 mb ram to Winblows vm.
Virtual Box is non-OSE ed., did not crash.

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
