[Kubuntu] Upgrade Tool Crashed

Binary package hint: update-manager

Fresh feisty install and try to upgrade to gutsy using adept_manager.

If I run kdesu "adept_manager --version-upgrade" after a few "Next" clicks I get the following error.
When I downloaded update-manager (sudo apt-get install update-manager) and run the command "sudo update-manager -d" the same window comes up again after some "Next" clicks but the upgrade seems to continuing fine...
