[Pharo-project] LogicalFont deepCopy infinite loop with Arial font

Hi all, I would like to improve the PreferencesBrowser so that it includes standard Fonts preferences (see joined snapshot). It's almost done except that, if a preference font is set to Arial, clicking on Save button leads to an infinite loop. To reproduce it, set button font to Arial-12 and Preferences standardButtonFont deepCopy. Cheers alain
