OK, I think this is the same problem that I found when trying to use hgview
(shows up when using qscintilla):

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import PyQt4.Qt as Qt
from PyQt4.Qsci import QsciScintilla

application = Qt.QApplication([])
qs = QsciScintilla()
qs.setMarginWidth(1, '000')

# Local Variables: ***
# mode: python ***
# End: ***

gives:

gav at zombie ~ $ python 041201.py
Traceback (most recent call last):
  File "041201.py", line 9, in <module>
    qs.setMarginWidth(1, '000')
TypeError: arguments did not match any overloaded call:
  QsciScintilla.setMarginWidth(int, int): argument 2 has unexpected type 'str'
  QsciScintilla.setMarginWidth(int, QString): argument 2 has unexpected type 'str'

And if you replace
qs.setMarginWidth(1, '000')
with
qs.setMarginWidth(1, Qt.QString('000'))
you'll get

gav at zombie ~ $ python 041201.py
Traceback (most recent call last):
  File "041201.py", line 9, in <module>
    qs.setMarginWidth(1, Qt.QString('000'))
TypeError: arguments did not match any overloaded call:
  QsciScintilla.setMarginWidth(int, int): argument 2 has unexpected type 'QString'
  QsciScintilla.setMarginWidth(int, QString): argument 2 has unexpected type
'QString'
