Bug 280390

Application: krunner (0.1)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.8.0
Operating System: Linux 2.6.40.3-0.fc15.x86_64 x86_64
Distribution: "Fedora release 15 (Lovelock)"

-- Information about the crash:
- What I was doing when the application crashed:
1. I ran KRunner with --graphicssystem raster, Qt 4.8 beta, and I tried to type some text in the box.
2. Boom.

- Custom settings of the application:
Qt 4.8 Beta 1
--graphicssystem raster.

You can reproduce this all the time, with the settings provided above. With --graphicssystem native KRunner works well, but exhibits some graphic glitches (Qt bugs).

The crash can be reproduced every time.

-- Backtrace:
Application: Interfaz de ejecución de órdenes (krunner), signal: Segmentation fault
