SubversionException: ("Can't get entries of non-directory", 160016)

When attempting to branch from a private repository, I get the following error:

4.318 return code 4

After a bit more digging with -Dtransport, I found that the culprit is a *file* that has been placed in */tags/.

It would be nice if there were a more useful error message here with a workaround to ignore tags/branches (if one exists)?
