Spy & Pharo-1.4 MONLinearColorNormalizer>>#minimumValue: intermittent error

FYI -


Sometimes when running an analysis the calculation to set the color of a
box in the view (Roassal/Mondrian ?) gets messed up because the result
of the MONLinearColorNormalizer>>#minimumValue: send is 'Float infinity
negated'


I'd guess that for that method you'd never want it to be below 0 or at
least bounded in some fashion..


I have not seen the error happen twice in a row.
