Qt Version: 4.8.1
Operating System: Linux 3.2.0-29-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

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

I was looking at the author information for Mouse Mark in Desktop Effects. When I clicked the close button of the credit/author dialog (not the Desktop Effects window), it crashed.

Expected: No Crash
