[issue3349] TypeError: 'NoneType' object is unsubscriptable

[William Leader]

New submission from William Leader <william.leader at gmail.com>:

I was attempting to test the conversion of our Subversion repository. I had created a copy of our repository using 
svnsync to my Windows XP (32 bit) workstation. When attempting the convert the following output is displayed. This 
happens every time on my workstation. I'm not sure how to create a reproduce-able test without providing you the 
repository, which I am unable to do.

Given that the last line in the call stack is a call to parselogentry, I suspect that one of my revisions has something 
in the log that the parser can not cope with. Perhaps if there were a way to identify which revision it was working on 
when it failed, I could examine the log for that revision and that would provide a clue as to what is going wrong.
