Hi guys. I am running some tests with Fuel. In such test I create classes and traits. The problem is that I get a: "MessageNotUnderstood: receiver of "isProvided" is nil"
Everything starts (it seems) when I do #addToComposition:�� and I receive a MethodRecategorized event and RPackage calls #systemMethodRecategorizedActionFrom:
There, the problem is with� ->� method isProvidedByATrait
the class of the method is 'AnObsoleteClassForTestToBeDeleted1'
And the error finally arrives to #providedLocatedMethod where it does "each method isProvided"� the problem is that "each" is a RGMethodDefinition with everything in nil except 'name'� and 'annotations'.
I attach PharoDebug.log.
Any help is really appreaciated.

Thanks,
