Description of problem:
The notification icon appeared, telling me updates were available. I clicked on
"review" to check what was to be updated. I checked the details for each
application to update with success, except for the one which is yum. When
clicking on the "yum" package, gpk-update-viewer crashed.

Version-Release number of selected component (if applicable):
gnome-packagekit-0.1.12-13.20080516.fc9.x86_64

How reproducible:
Always, but only for this particular package.

Steps to Reproduce:
1. review updates
2. click on the yum package => crash
3. the notification icon remains, and I can do it again
  
Actual results:
the update viewer crashes

Expected results:
it should display the yum package update details.
