Moving Starred file leaves "ghost" file in favorites:///

Steps to reproduce

1. Star a file.
2. Move the starred file (to Trash or some other location, indexed or not)
3. Switch to favorites:///

Expected result

Moved file is is properly listed in favorites:///, unless it was moved to Trash.

Actual result

An unknown-typed file with no name is listed in favorites:/// instead. Its thumbnail (if any) is identical to the moved file. Using "Open Item Location" will open the location the file was moved from in step 2.
