Version:           unspecified (using KDE 4.4.4) 
OS:                Linux

Dolphin often crashes. I am not sure what makes it crash, so no steps to reproduce can be given. But it happens a lot since I either
- updated to a newer KDE version
or (more likely)
- activated Nepomuk in KDE

see console output below, which is hopefully useful.
Dolphin version 1.4, KDE version 4.4.4 "release 3".

Reproducible: Sometimes

Steps to Reproduce:
Unfortunately, no idea. See above.

If this isn't helpful enough, I'll install some debug libraries to get a real backtrace. Anyway, the KDE crash manager (is that "Dr. Konqi" ?) didn't start.
