Test failure on Python 2.7 alpha 2

I get one (just one!) test failure running the test suite on Python 2.7 alpha 2:

The only difference is in the weight of the Platypus. We're expecting 2.29something but now getting 2.3. As the Platypus is actually added with a weight of 2.3, I think the change is due to improved string/float rounding in this version of Python (noted as one of the 3.1 changes backported to 2.7 here: ​http://docs.python.org/dev/whatsnew/2.7.html#python-3-1-features). I think we can fix this by simply changing the weight here to be one that won't exhibit this anomalous behavior between different Python versions?

Your solution LGTM.

I'll do that then.

(In [12132]) Fixed #12562: Made Platypus just a tad lighter so it does not trigger noticing version-dependent differences in Ptyhon string/float conversions.

(In [12134]) [1.1.X] Fixed #12562: Made Platypus just a tad lighter so it does not trigger noticing version-dependent differences in Ptyhon string/float conversions.

r12132 from trunk.
