See what in your directory , the "bad cure" should produce a .txt file named
So , here you could do a forensic analysis of if any obsolete go caught

The complete is  replace ' AnObsoleteUrl' by what was the last in your image
(the last saved to clasesObsoletas.txt)

Instead of "nil" , you could put String new, but the image could blow also.
Sometimes if you change to arreglar _ (Smalltalk obsoleteClasses) reverse,
all obsolete goes.
Or you could need put a self halt and do class by class
It's black art, and we have different spells.
I do many times and if the procedure completes, never have problem again.

Sounds like someone delete class badly,

I don't know what Squeak are using you
> SmalltalkImage current fixObsoleteReference
> this one drop out two classes
So if you save in this point, you have a cleaner system .

I afraid what the Pavel tip is more tedious but safer.
Could send mail whit what Smalltalk obsoleteClasses prints ?

Good luck
