[Pharo-project] Smalltalk condenseChanges -> 'Invalid utf8 input detected'

Hi: I am trying to evaluate a Smalltalk condenseChanges but I am getting a 'Invalid utf8 input detected' This seems to be this bug: http://code.google.com/p/pharo/issues/detail?id=830 but that bug seems to be fixed. I can still reproduce it. Can anyone confirm this ? I attach log. Cheers, Mariano
