I think the principle was covered in another response, but the only way
you can get history is to start from the highest rev and follow
backwards, and you are asking it to start from head, which is impossible.

In this case the file does exist in head, and you wouldn't have to
specify the peg revision at all. Subversion can track the 'copy-from'
backwards and knows it is that same item. But the name isn't what ties
them together. You could just as easily have copied to a different name
in head and asked for the log with the new name there and you'd get the
same history.
