OS: Leopard 10.5.1
OmniFocus: 1.0 Vapourtrail (v50.0.95014)

Problem: from a few updates ago, OmniFocusMetadataImporter is stuck in my Mac OS trash can and I can't delete it because, it reports, the item is in use.

I've gone hunting around for the process that calls this file - no avail.

Anyone else?
