      Since installing this change the problem
      has not re-occurred.  I took the change out and it occurs
      constantly. 
  
   This is quite puzzling.

You're telling me.  I spent over an hour trying to figure out how
that was possible before asking for suggestions on what next.
  
      When which-function-mode turns itself off the error which
      the code below implies will be reported is nowhere to be
      found in my *messages* buffer.  I.E.
      "Error in which-func-update: ..."
  
   What is the rest of the message? 

It's not there.  I wish I knew. 
But I spent a couple more hours.
I believe this is the original error triggering the other error.

* error("Error in which-func-update: %s" (error "This buffer cannot use 
`imenu-default-create-index-function'"))
  byte-code("???\"? [info which-func-mode -1 error "Error in 
which-func-update: %s"] 3)
  byte-code("????????É\n????
  which-func-update-1(#<window 43 on *Occur-N50S*>)

This error is consistent with the symptoms.  
It typically turns itself off when I'm in an occur buffer.
