Comment 2 for bug 1370693

Actually, on further investigation, it seems that pdf2svg is a little bit nicer than pstoedit: it doesn't produce so much unnecessary "noice" on its stderr. So attached is a new patch which incorporates that offered in https://bugs.launchpad.net/inkscape/+bug/367446 along with my patch to handle pathnames with spaces in them.

Note that the patch to inkex.py is purely for Python 3.x compatibility (where x >= 3).
