Cool--always happy to reveal a bug.
;) And I'm always happy to receive bug reports, because it feels like just being one step closer to a bug-free release.
Let me know if I can help in testing a fix.
Thanks for the offer. I noticed that the error was caused by an old assertion in the code..

I removed this check, and not any of our W3 and JUnit update tests complained. It's tempting to simply leave it like that, but I'll have a closer look at this tomorrow.
I'll tell you once this can be tested.
