Failing tests print base64 encoded values

When I run tests using the Django test runner, failing tests are displaying strange values in the failure messages. I have something equivalent to "self.assertEqual(1, 2)", which shows up when just running tests from the console as:

AssertionError: 1 != 2

When I try to use the Django test runner in Pycharm, the output is:

File ".../pycharm/teamcity/diff_tools.py", line 37, in _patched_equals
raise error
EqualsAssertionError: MQ==|Mg==|

It looks like whatever is in 'diff_tools.py' is base64 encoding values before they get printed to the console? Is there a way to disable this layer so I can just see the raw exception?
