Description Christoph Feck 2011-10-18 13:28:43 UTC 
Application: krunner (0.1)
KDE Platform Version: 4.7.2 (4.7.2) (Compiled from sources)
Qt Version: 4.8.0
Operating System: Linux 3.1.0-rc9-1-desktop i686
Distribution: "openSUSE 12.1 Beta 1 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:

To reproduce the crash, you have to remove the setGraphicsSystem call from main.cpp. Now, whenever the results list should appear, it crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Run Command Interface (krunner), signal: Segmentation fault

Git commit 190413deb022edfd2b9e731c0fd350441511920a by Christoph Feck.
Committed on 18/10/2011 at 15:41.
Pushed by cfeck into branch 'master'.

Fix painting on pixmap that already has a QPainter attached

The code should use QWidget::render() instead of redirecting, but
this simple move fixes the crash, hopefully also on Windows (where
native == raster).
