Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.9-174.fc12.x86_64 x86_64

What I was doing when the application crashed:
I was viewing a folder full of files in Dolphin, trying to decide which to open. I was absent-mindedly moving my mouse rapidly in circles over the icons (Dolphin was in Icon View), when Dolphin crashed. I don't know exactly what caused it and further folder-viewing and mouse-circling has produced no further crashes, so I hope the backtrace is helpful.

 -- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
