[squeak-dev] [trunk] Getting MNU UndefinedObject>>:do when trying to build trunk from scratch

I'm building the trunk image from stratch, and I get (for me) a weird error. Background:

Do you have a stack trace? Quoting a single line of code is not enough
context to figure out what is going wrong.

What is the best way to get a stack trace worth sending? I used
errorReportOn: and got this:

Close. There is a SqueakDebug.log that you can send. But the information
is clear enough - it looks like it's SqueakMap causing trouble again,
probably during flaps reinitialization. Try destroying the global flaps
(World Menu >> Flaps >> Destroy All Shared Flaps) before you update.
This should fix it.
