 I'm running on Windows 7 x64. I followed the install documentation on
 Buildbot and did some research on the issue I'm having and haven't found a
 solution yet. When I do a force build, everything works fine. I'm using
 GitPoller. When it tries to poll for changes, an exception is thrown; why?
 Let me know if I can supply any more information. Here's what I'm getting
 on the master's twistd.log every 5 minutes:

 Also, here's the relevant portion of my config file:

 {{{
     from buildbot.changes.gitpoller import GitPoller
     c['change_source'] = []
     c['change_source'].append(GitPoller(
             repourl='https://github.com/solstice333/BuildbotTest.git',
             branch='master',
             pollinterval=300))
 }}}
