Application that crashed: plasma-desktop Version of the application: 0.3 KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1)) Qt Version: 4.5.1 Operating System: Linux 2.6.30-6-generic i686 Distribution: Ubuntu karmic (development branch) What I was doing when the application crashed: Everytime in KDE 4.3 Beta 1, when I try to hover over the /root/ folder, or any folder when you ls into get "permission denied" in a terminal, Plasma crashes. The new panel does come up, and it displays that the folder can not be accessed, Plasma crashes.

This looks a lot like a Qt bug to me.
I can't reproduce this bug with the current SVN version of KDE. It was probably fixed in revision 976868. If you can still reproduce this bug in beta 2, which will be released next week, please re-open this bug report.
I tried it in Beta 2 and it still crashes. I installed more debug packages on my system, and here is the backtrace: I don't see a "reopen" option, or mark as open...

I've reopened the bug (it's done by changing the status), but I'm afraid I still can't reproduce it.
*** Bug 197223 has been marked as a duplicate of this bug. ***
As I know to reproduce bug you only change folder view from /root/ directory. In this case I cannot confirm this bug in KDE 4.2.4: kdelibs-4.2.4-r2. If I do this in Folder view widget I see: "Cannot enter into the /root/ directory". It's right.
