In our data model, Directories never have any permission bits set. That's what's being (confusingly, I guess?) reported by the webapp. That's not specific to deposits at all.

I can't seem to navigate the __MACOSX directory of the first directory, which smells like a bug of the webapp; but navigating the other directories works just fine.

Ok thanks, so it seems more an issue about presentation.

Indeed, I had issues navigating that directory too...

Ack, I will remove the display of permission bits for the directories then.

I will also look at the navigation bug.
