The NUnit plugin throws a NullReferenceException when attempting to parse the .xml report produced by Unity3D's test runner:

Here is the actual error from our build logs:

The job is run on a slave node running on Mac OS X 10.11.6. So far I have been unable to publish a single report with the NUnit plugin. I have confirmed that the NUnit plugin does find the report file, the failure happens after the parsing has started and a temporary-junit-reports folder has been created (containing a simple temp-junit.xml with barely no contents, see below)
