Unable to run coverage with engine as "Chrome"

First of all, thanks to you Matthew and all contributors of Chutzpah. This is a fantastic test runner.

Coming to the issue - I have some unit tests which fail for the reasons seen below. If I run them by specifying engine as Chrome there are no issues and all 18 tests pass.

However, if I run a coverage with this command "chutzpah.console.exe /coverage /path "BcrConfigManagerTest.js" /engine "Chrome"", the run fails with the below seen errors

Are there any issues with the coverage library Blanket.js to run on Chrome. If so, how would you suggest I could get coverage numbers from these tests?
