Blast.app from the past

I rather liked this bugfix affecting OS X 10.5:

"Launch Services is an API to open applications or their document files or URLs in a way similar to the Finder or the Dock. Users expect that uninstalling an application from their system will prevent it from being launched. However, when an application has been uninstalled from the system, Launch Services may allow it to be launched if it is present in a Time Machine backup. This update addresses the issue by not allowing applications to be launched directly from a Time Machine backup. [...]"

There’s something fun about this collision between the nice, straightforward world of the Desktop, the Dock and their friends and the freaky world of backups, revision control and the like. I haven’t got hold of 10.5 (yet) but I'm looking forward to seeing how Apple have resolved this potential mindbender inside a GUI.
