Hi! I was trying to load ConfigurationOfPharo in Core 1.2, so we can (slowly) get a Dev image. So It began well, but when it reached AST-Core-lr.84, it raised up an exception: "subscript is out of bounds: -1" It is mainly caused by CommentReference>>parseTimestampFrom: Which has the next comment: "Timestampstrings can be of the form: <authorname><date><time>. <authorname><date> <date><time> <date><time><authorname> <date><authorname> <historical>" The string timestamp is '<historical>' indeed, but it does the follow check: ^ (aString isEmpty or:[aString = 'historical']) ifTrue:[DateAndTime new] ifFalse:[ *here comes the error ...* Shouldn't that check be ^ (aString isEmpty or:[aString = '<historical>']) ?? Cheers, Guille
