Thanks for the report. I've fixed it in 87ee542.

Is there a particular place where you're calling `mode-line-string' on a 
directory, though?

The return value in this case is poorly defined, because the string 
includes a character indicator of the current VC state of FILE, and the 
VC API doesn't define VC states for directories.
