I believe it would still be prudent to verify that image 
7f8bb099-9a18-4e89-bf48-57e56e5770d2 is supposed to be missing, by running 
the disk info tool from:
   https://bugzilla.redhat.com/show_bug.cgi?id=1306741.

Once we verify that it's ok to remove the image, then I'd proceed to clean 
up the db records via the image cleanup sql script.

Thanks,
Greg
