Steps to reproduce the behaviour

1.run grunt watch - tests run successfully
2. change a test file
3. it attempts to rerun but throws error (shown above)

Keeping all the dependencies and configuration the same and just downgrading karma to 1.0.0 prevents the issue.

@main-kun your issue should be fixed by the latest release of karma-junit-reporter, 1.2.0.

@mcgraphix a mitigating fix can probably be done to karma-htmlfile-reporter similar to the patch to karma-junit-reporter recently done, but the root of the issue in karma itself is #1292 as mentioned by @stramel.
