This is really strange Bernnard. But one thing to remember is that
the 13680 image has a corruption. Search the mailing list for
subject: "(Environment named: #Smalltalk) trap in 4.5." That thread
explains the corruption related to having String-key's in an
Could you try updating your 13680 image from the 'squeak45' repository
FIRST, to ensure you get my fix for that BEFORE you change to trunk.
This will take you to 13687. THEN you can change your updateUrl to
trunk and update from there. Does that help on your end at all?
I just tried it both ways but didn't experience the issues you did
whether I updated from squeak45 first or not. No dirty packages, and
your Error catch select: produced no errors but returned an empty
collection for me.
But I'm going from Linux and using the 2776 VM which ships with 4.5.
I think that is the most reliable VM right now. I'm curious if you
reproduce my steps above whether it reproduces my success?
Let's not give up on this! It sounds like there's a problem lurking,
possibly only in Mac..??
