Python error

Hi,

Archlinux. Wiithon compiled and installed (ok) from source.

When I try to run:

/usr/share/wiithon/wiithon.py

I get:

Entity: line 29: parser error : Opening and ending tag mismatch: module line 18 and pr
</pr></rojo><br />
     ^
Entity: line 29: parser error : Opening and ending tag mismatch: pr line 17 and rojo

            ^

            </margin12>
                       ^

        </xhtml>
                ^
Entity: line 35: parser error : Premature end of data in tag xhtml line 2

        ^
Error in sys.excepthook:
Traceback (most recent call last):
  File "/usr/share/wiithon/gui.py", line 397, in excepthook
    self.alert('error' , mensaje_xml, excvalue, xml=True)

    if ret is None:raise parserError('xmlParseDoc() failed')
libxml2.parserError: xmlParseDoc() failed

Original exception was:
Traceback (most recent call last):
  File "/usr/share/wiithon/wiithon.py", line 91, in <module>
    App()
  File "/usr/share/wiithon/wiithon.py", line 75, in App

    return (int(group[2]) in os.getgroups())

Thank you in advance
