Error running mach:

    ['test', 'browser/devtools/webconsole/test/browser_webconsole_block_mixedcontent_securityerrors.js']

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.

You should consider filing a bug for this issue.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

UnboundLocalError: local variable 'result' referenced before assignment

    test_objects=tests, **m['kwargs'])

--------------------------------------

AFAICT from the manifest and my directory's state, the test exists and should be runnable on this platform.

This is on Windows 8.1, with 3 patches applied on top of 216800:da918fa50e5f on fx-team.

The test runs normally if I substitute "mochitest-devtools" for "test".
