Version:            (using KDE KDE 3.1.3)
Installed from:    RedHat RPMs

I opened konqueror window in home directory,  changed to new directory by typing a location in address bar (/usr/share/wine-c/Program files/Visio. Then while trying to enter next directory (Solutions) konqueror window has crashed. 
I could not recreate this behavior. 

Here is a backtrace:
