Just a guess (I'm on mobile seaside) but maybe it is a Windows specific
issue, since the code has been developed and reviewed by Linux devs only.
My guess is based on the path seen in the error message, believe it should
be "file://c:/..." (Note the double slash while the error msg reports a
single one)
Cheers
