Cannot handle GVFS URIs on drag-and-drop

Plank cannot handle GVFS URIs on drag-and-drop, neither for adding to dock nor for passing on to an application. A screencast of the problem is attached.

The filename pantheon-files exports to clipboard in this case is "archive://file%253A%252F%252F%252Fhome%252Fserioga%252F%2525D0%252597%2525D0%2525B0%2525D0%2525B3%2525D1%252580%2525D1%252583%2525D0%2525B7%2525D0%2525BA%2525D0%2525B8%252Fubuntu-12.10-desktop-amd64.iso/md5sum.txt"

For completeness' sake, drag-and-drop to Firefox results in the same URL, while drag-and-drop to pantheon-terminal produces '/home/serioga/.gvfs/ubuntu-12.10-desktop-amd64.iso/md5sum.txt' (including the apostrophes).
