Hi
Just looking at the test that is failing (#testSmalltalkGlobals) and
the error (a DoIt method can't be materialized), it makes me wonder
why a method is being serialized in this method. There is the problem,
I guess.

To reproduce what the test is serializing you can inspect:

| anObject aStream |
anObject := Smalltalk globals.
aStream := (MultiByteBinaryOrTextStream on: '') binary.

(FLSerializer newDefault
   serialize: anObject
   on: aStream)
   objects.

I get this in Pharo:

an Array(a SystemDictionary(lots of globals) true false nil)

What do you get?

Maybe it has to be with the environment? I have no idea of that.

Best regards,
Martin
