How to purge "You can’t open the application “q.app” because it may be damaged or incomplete" status?

Question

I am trying to create a simple .app bundle. I made a mistake in the Info.plist and the finder shows it with a "barred" sign over the icon, and I get that message when I try to click over it. I fixed the error in the Info.plist, I am sure 100 % the bundle is now ok, but I still get the error message. It seems like Finder detects a broken app and caches it. How do I reset this cache? Even copying the bundle does nothing. I tried tarring and untarring it, and it works, but there must be some magic trick. I thought it was extended attributes, but xattr shows nothing.

Have a look at this tutorial: http://reviews.cnet.com/8301-13727_7-10330759-263.html

My guess is the that the first solution will work: update the prebinding.
