The new update details are pretty hot. However when it is combined with the suggested reboot message it almost looks like the reason it is suggested you reboot is /because/ of the content in the details. http://jkeating.fedorapeople.org/confusing-pirut-message.png
Open to suggestions... making it two dialogs seems pretty lame, though.
Due to lack of anything better, split into (potentially) showing two dialogs.
