Comment 6 for bug 250901

I'm having a similar issue, and like the above suggestion, I've set the limit to -1.

File "/usr/lib/python2.5/site-packages/bzrlib/plugins/email/__init__.py", line 98, in branch_post_change_hook
    params.branch.get_config(), local_branch=None, op='change').send_maybe()
  File "/usr/lib/python2.5/site-packages/bzrlib/plugins/email/emailer.py", line 248, in send_maybe
    self.send()
  File "/usr/lib/python2.5/site-packages/bzrlib/plugins/email/emailer.py", line 185, in send
    self._send_using_process()
  File "/usr/lib/python2.5/site-packages/bzrlib/plugins/email/emailer.py", line 198, in _send_using_process
    message = self.body().encode('utf8') + self.get_diff()
TypeError: cannot concatenate 'str' and 'NoneType' objects
