I've updated .travis.yml with addition of latest release of django (1.4.3). There's also fix to make pep8 happy.
Fixed indentation to conform to PEP8
Added latest release of django to Travis configuration
Can you add Django 1.5 as well?
Added django 1.5.0 to Travis configuration
FYI I believe this is superseded by #19, which fixes a few other whitespace-related errors and updates to the latest Django versions.
