Application: krunner (0.1)
KDE Platform Version: 4.4.90 (KDE 4.4.90 (KDE 4.5 RC1))
Qt Version: 4.6.2
Operating System: Linux 2.6.34-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
Since upgrading to 4.5 RC1 all plasma actions seemed to be really sluggish (e.g. showing an autohidden panel, showing a menu, ...). I suspected the newly introduced blur effect to cause this, so I've opened the "Desktop Effects" KCM using krunner (input: effec).

After disabling the blur effect and applying the settings, I've received this backtrace:

-- Backtrace:
