-- 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.
