patch

Description of problem:
Sometimes an exception is thrown:
  'GitNode' object has no attribute 'log'

Version-Release number of selected component (if applicable):
trac-git-plugin 0.0.1-5.20090628svn3369.el5

How reproducible:
on some repositories always, on others never.

Steps to Reproduce:
1. browse source via trac on an affected repository
2.
3.
  
Actual results:
exception trace

Expected results:
normal source browsing

Additional info:
The exception is thrown because self.log is accessed in a GitNode object while that object has no log.

As it's a debug log only, we can easily get rid of it.
I wrote a patch to do just that
