Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.31.1 x86_64
Distribution: "Fedora release 11 (Leonidas)"

What I was doing when the application crashed:
Created a soft link to a just-mounted ext4 directoy. Click on new link in folders. Kaboom. Might be a thread problem, that message went by while the crash assistant started.

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