I see two possible solutions for the problem.

1) Replace non-printable, space and '/' characters for example with '_'.
   '/' should be replaced anyway.

2) Apply the patches in
   http://lists.freebsd.org/pipermail/svn-src-all/2013-January/063661.html
   to allow spaces again. I haven't committed the patches because I
   think that there isn't full consensus that it's right thing to do and
   also I personally prefer not to have spaces in device names.
