It means that it tried to generate a wxPython GUI for the options, the
code which generates the GUI executed the command with the
--interface-description flag to get a list of the options in XML
format, then passed the output to the Expat XML parser. Unfortunately,
the command failed to execute, so no XML was generated, and Expat
complains about not receiving valid XML.

IOW, the error message is accurate but quite useless. To get useful
information, you'll need to run the script manually from the command
line. Try running it with the --help option initially.
