Qt Version: 4.7.4
Operating System: Linux 3.0-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I was clicking around and playing with the shadow angle in a version 2.4 compiled yesterday from git, when I got to the blur radius, and went below a certain radius, not sure which one it just Crashed to desktop.
I was also seeing it tried to switch angle when I was toying with the setting below it before reaching blur.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Karbon14 (kdeinit4), signal: Floating point exception
