I manually ran and submitted a passing report on a win32 5.30.1 64bit, so my guess is that it was a bad installation or something went wrong in the smoker-environment.
While I was looking to see if it showed up yet in tail/log.txt, I saw that gregor had just submitted a second run: it looks like when run manually, it was passing for him, too. Other than the path (which has extra stuff because it was manually run), and not running in the smoker-environment, I cannot tell what the difference is between the two.
update: ahh, mine was 5.30.0, not 5.30.1... Still, it gives you more passes. :-)
