KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.1
Operating System: Linux 2.6.35.12-88.fc14.i686 i686

-- Information about the crash:
- What I was doing when the application crashed: Viewing comics with firefox, destop zoomed in. Crash occurs after perhaps 3 minutes of zoomed operation, repeatably.

- Custom settings of the application: System settings: destop effects enabled, zoom enabled.

Video card is PNY (nVidia) Quadro NVS 290 X16. nouveau driver. 2 displays, over/under. System crashes and does not seem to respond to keyboard or mouse. Reset needed to return to operating computer.

The crash can be reproduced every time.
