Something seems to go wrong while reading the test results.
What version of NUnit are you using (not the dll version referenced in your test project, but the version of NUnit you configured for use by OpenCover.UI)?

This looks like a duplicate of #42

I get the same stack dump today. I'm using VS2015 and NUnit 2.6.4 (latest 2.x prod version), with OpenCover configured to use nunit-console.exe
