One more try to get the FilePath usage right.
One more try to get the FilePath usage right.

I was using:
  FilePath("/")

This only works on linux/mac because it is an ascii string and can't be
coerced to a wide string.

Reworked the code to put the hack into the string portion.

BUG=none
TEST=none
