[Buildbot-devel] exceptions.UnboundLocalError: local variable 'revision' referenced before assignment

[Marijn Vriens]

Hi all,

I get the traceback below when clicking on a specific build URL. An example
of the traceback can be seen here:
http://protocultura.cl/buildbot/builders/quickbuild/builds/3

I didn't mess about with the html renderer, so I fear it's an out of the box
failure. Any idea what might be going on?

Buildbot master is at 0.7.11p1
$ ~/pyenv/bin/python --version
Python 2.5.2
$ uname -a
Linux gans 2.6.24-19-xen #1 SMP Sat Jul 12 00:15:59 UTC 2008 x86_64
GNU/Linux

Regards,
      Marijn
