Looks like a problem with component seperation before use.

Your hack is an OK workaround; is it possible to get rid of
the double "//" in the original code?  Only multiple "/"
in intermediate path compnents are supposed to be collapsed.

I don't know if FreeBSD ever intends to support POSIX name
space escapes for things like extended attributes, but if
it does, this will come back to bite us later.  8-(.
