Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.1 (KDE 4.3.1) "release 6"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-0.1-default x86_64
Distribution: "openSUSE 11.2 (x86_64)"

What I was doing when the application crashed:
Dolphin crashes out of the blue after having opened one directory and opened a pdf with Okular.  The computer was then left for a time and on unlocking the screensaver the crash reporting assistant was shown. 

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