Bug 284790

Application: kcmshell4 ()
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
I was chatting (IRC) using ChatZilla in Firefox. I also surfed the net.
While I was doing this, sudo rsync -vcraE was running in a terminal in the background.
Also, I moved a NTFS partition within an extended partition on an external HDD using the KDE partitionmanager in the background.
I also noticed that running bleachbit using all options (maybe only a few of them is needed) crashes EVERY KDE tool and program currently running on the computer as soon as you use them again.
