I'm getting a few failures like this one with the released version of the aruba 0.3.2 gem. The intend of the feature seems to be fulfilled, just not the order in which the results are shown. I'm not sure to what extend this is considered to be a problem.

This is using "ruby 1.8.7 (2011-02-18 patchlevel 334) [x86_64-linux]". Please let me know if you need more details.
