Version:            (using KDE 4.2.3)
OS:                Linux
Installed from:    Ubuntu Packages

Steps to reproduce:

1 - Go to / (directly or via Places menu)
2 - Right-click in an empty space
3 - Click on properties
4 - Crash

This only happens in /, other directories like /etc and /usr work fine. It's mounted in a different physical partition from /home, if it helps

Strigi isn't enabled

Backtrace
