From upstream: "This does not happen anymore with 2.22, (you get an error dialog saying "Couldn't display "#".". It might have been fixed in the transition from GnomeVFS to GIO during the 2.21 development cycle. Closing this report as OBSOLETE, please reopen it if you still find this bug with Nautilus >= 2.22,
thanks!"
I confirm this behaviour on Nautilus 2.22.0, so closing as fix released.
