Description of problem:
I installed fc6 yesterday from scratch.
I used yumex to do an update and did a select all.
yumex then ran for about 45 minutes and appeared to be near completion when
the window exited.
I tried starting yumex again and it again exited.
I rebooted and ran yumex again and received exception and request to submit bug.
I read the only yumex bug I found and the trace didn't match so I'm submitting a
new bug.

The text from the exception box:
Component: yumex
