Application: dolphin (1.4)
KDE Platform Version: 4.4.00 (KDE 4.4.0) (Compiled from sources)
Qt Version: 4.6.1
Operating System: Linux 2.6.32.8 i686
Distribution: "Gentoo Base System release 2.0.1"

-- Information about the crash:
I was in the middle of some large mv and cp, and wanted to test some automagical rename oneliner, so, in the terminal tab (?) (it's under F4) changed dir to /tmp/foo. Tested what I wanted to test, and I tried to return to my previous dir clicking on the dirname in address bar (that didn't refresh after manual dir change in terminal, so that was the quickest way ;). And here I am with the crash.

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