The current 6.0a image as downloaded from Squeak.org <http://squeak.org/> (Squeak6.0alpha-17606-32bit.image [Dec 21, 2017]) contains this anomaly and updating doesn’t help.

I just manually performed a bunch of diffs on the Tools project in the MC repository browser (I imagine there is a better way to do this).

It looks like Tools-eem.750.mcz is the last to have MethodContext>>inspectorClass in its *Extensions -> *Tools->Inspector.  Tools-eem.751.mcz is the first to have Context>>inspectorClass there.

Commit comment for Tools-eem.751.mcz (30 March 2017):

"Commit the essential cange of reference from MethodContext to Context before commiting the Kernel that does away with MethodContext."

Does that help?  

I have some suspicion, from my less-knowledgable viewpoint, that since MethodContext>>inspectorClass is in an *Extension, some subsequent commit could have come through in a different project, hadn’t updated to Tools-eem.751.mcz, and was missing Context>>inspectorClass?  But what do I know...

Thanks,
Tim
