Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2)) "release 142"
Qt Version: 4.5.2
Operating System: Linux 2.6.27.23-0.1-default i686

What I was doing when the application crashed:
First I start dolphin and then I open another tab. Then I close the tab with the middle mouse button and dolphin crashes.

This happened in KDE 4.3 RC1 and now also in RC2 from openSUSE repositories. I don't remember that this happened before I updated to 4.3 RC1.
