Description of problem:
During an install of Fedora 16 Beta RC1 dvd, I got unhandled exception when trying to install. How I replicated it was the following:
1) Go into custom install and deselect gnome items, select kde items. Try to install but get dep issues.
2) Go back and turn on updates-testing. Go back and repeat select/deselect steps. Try to install and get dep issues.
3) Go back and turn on main repository. Go back and repeat select/desect issues. Try to install and get dep issues.
4) Go back and select minimal install. Unselect main and testing updates repository. Press go ahead. Get crash.
