Comment:

 Nils, I can reproduce your bug:

 --With version '0.5.3.dev3189'
 0.0
 2.68490579098e-18
 Should be zero but is  0.00402954093259

 --With version '0.5.3.dev3162'
 0.0
 2.68490579098e-18
 Should be zero but is  1.45428428374e-18

 Since this is a recent bug, it shouldn't be too hard to isolate.  Thanks
 for the error report, I'll look into it.
