Looks like you have a pointer to an obsolete class.

I use this bit of code from his post when I have the same problem 
(pointers to obsolete classes):

  SystemNavigation default obsoleteClasses isEmpty
         ifFalse: [SystemNavigation default obsoleteClasses
                 do: [:each | [PointerFinder on: each]
                         on: Error
                         do: [:error | Transcript show: error; cr]]].



Maybe you can use that in a workspace of your messed up image to delete 
the pointers to the obsolete classes and that will free things up.
