Just as with the FF vs. Chrome, a new one: 

search.feature contains the line 

And The URL of the page should contain "Main%20Page"

All of a sudden this fails on the Cloudbees host but passes on my local machine.[1]

We should probably decide on a rule for URL checking, the tests are all over the place with that.
