Using Fedora Linux 8 on a Dell Dimension 2350.

Description of problem:
After adding and removing a ton of packages (too many to remember, sorry) and clicking Apply, it crashed and told me to report the crash data, so here it is.

Component: pirut
Summary: TB80d77535 HalCD.py:124:umount:NameError: global name 'DBusException' is not defined
