Description of problem: The package kio_p7zip is in Fedora Extras 6, but not available in Fedora 7, and there's no pending update for it in Bodhi. Please submit an enhancement update for the new package to fix the upgrade path. Version-Release number of selected component (if applicable): kio_p7zip-0.3.1-4.fc6
Well, I have to admit that I'm not entirely sure how the updating system works. I thought I added kio_p7zip to F7.
