[Pharo-project] Collection new printString make the image hanging

Hi, I was coding in Pharo1.3 Latest update: #13315 By evaluating some tests again the emergency evaluator pop up (Pharo doesn't like me lately :) ). This time at least I figure that some elements i use in the tests do not print properly: <error in printString: evaluate "collection printString" to debug> so if you do Collection new printString. the image seems to hang the only was to stop it is to do command period. In 1.4 at least the debugger pops up telling that "do:" should be implemented in a subclass. To make the image hang you should do SequenceableCollection new printString. I don't know if those are suppose to be bugs or my inappropriate use of Collection and SequenceableCollection. I just reported. Cheers, Fabrizio
