[Pharo-dev] removing the last class extension of a class does not reclassify the class in nautilus

Hi guys While refactoring critics and RB I got the following glitch. When I remove the class extension made by critics on RBRule, the RBRules were not systematically updated in the list of extension of the critics browser. It would be good to investigate this and https://pharo.fogbugz.com/default.asp?14561 BTW we should continue to simplify nautilus. :) Stef
