Effbot's SimpleXMLWriter fails when py2exe'd

[Erik Bethke]

Hello All,

So I have been using Effbot's XML stuff a lot!  And I have been using
py2exe, pygame and wxPython all mixed together...

I am getting this strange error log when writing XML files with his XML
writer.  It appears to be fouling up on the encoding, ONLY in the exe
version.  Runs fine and great as a python script.

What this does is leave the file hanging open...

I could write out the XML myself, but I would rather use his class...
any ideas why it broke?

Thank you,
-Erik

def SaveVocabTree( self ):
    ElementTree( self.vocabXMLTree ).write(self.currentPath,
encoding='utf-8')
