Bug 206945

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I have a Folder View widget on my desktop showing the contents of ~/Desktop.
If I hover the mouse over a folder that I have no rights to access, I see the message "Could not enter folder ..." and plasma-desktop crashes.

How to reproduce:
- add a Folder View widget and set it to display ~/Desktop

$ cd ~/Desktop
$ sudo mkdir somedir
$ sudo chmod 700 somedir

then hover the mouse over the "somedir" folder, trying to preview it's contents.
