That looks like a bug. Well, more probably a deficiency in the
implementation. file-find first determines tag for the file (by the name
given), and then goes to the pristine tree, gets it's inventory and
fetches the file. Since the file does not exist, the first step fails.

Extending that command should be considered. But I am not really sure
what would be the RightWay to do it. (It should be kept that file-find
and file-diffs are implemented by the same function).
