'NoneType' object has no attribute 'strip' - Pywikipedia-l

3 Jan 2010

Hi!
Do you have any idea why, using replace.py on some large dumps, I get 
this error message:

C:\pywikipedia>replace.py -xml:enwiki-20091128-pages-articles.xml
Please enter the text that should be replaced: impossibletofindword

     self.username = username.strip()
AttributeError: 'NoneType' object has no attribute 'strip'
'NoneType' object has no attribute 'strip'

I updated pywikipedia to the last revision with no results.
As you can see it does not seem to be user-fixes.py or regex-related.

Thanks in advance!
