Thanks for your report. I can verify that the EN_OS.usr file opens and
the TC_OS.usr causes a crash. Both files are written with an XML
declaration that declares an ISO-8859-1 encoding:

    <?xml version="1.0" encoding="iso-8859-1"?>

That comes from these few lines in zenmapCore/NmapParser.py:

    def write_xml(self, xml_file):
        xml_file = self._verify_file(xml_file)
        self.write_parser = XMLGenerator(xml_file)

where the encoding of the XMLGenerator defaults to "iso-8859-1" (see
http://docs.python.org/lib/module-xml.sax.saxutils.html#l2h-1924).

I think it's the time zone in the XML output that's not encoded in
ISO-8859-1. Maybe this can be fixed just by changing the output
encoding.

Run your scan again, like this:

    nmap -T Aggressive -sV -n -O -v 192.168.1.142 -oX TC_OS.xml

and then try to open the TC_OS.xml file in Zenmap. If it works, then the
problem probably lies with Zenmap rather than Nmap.
