Thanks a lot! This got me on the track to solve my problem with Toast and Popcorn (http://osx.kbot.de/comments.php?DiscussionID=842&page=1#Item_1).

I just wanted to add here that I didn't have to boot into single user mode. I simply ran the patcher as super user and that seems to have done the trick. I didn't even have to reboot - Toast and Popcorn opened fine the first time I tried after applying the patch.
