destructive bug: deleting a version deletes the master

This is reproducible with every image in my library. I have two versions of an image. I reject one version, then delete it. Now my remaining version shows a file offline warning. In other words, by deleting one of two versions — not the last remaining version, mind you — the master is being deleted.

I have tried all of the database repair/rebuild options multiple times, but this behavior persists and I am now afraid to delete anything. My confidence is blown.

Thank goodness for Time Machine, because this happened to over 2000 photos in one shot when I emptied the trash of what I presumed to be unimportant versions, only to watch with horror as 2000+ remaining versions sprouted the file-offline badge, but I was able to restore my entire Aperture Library in under an hour.

Any ideas on the root cause of this, or how to fix it?

I’m using a managed library.
