  I would say that the detail counts here.  Did you break a method?
Did you break a class definition?  Did you change a globally visible
object?  How many classes/methods affected?  The difference leads you
to different solution.

  The changes file is just a memory size optimization and the real
thing (including everything, such as methods) are in the image.  If
you overwrite a good image on disk with bad one, it is often a
problem.  (It is usually a nice idea to keep a good version of image
under a different name.)  If most of the development tools are still
working, and what is causing trouble is just method changes, you may
be able to revert the method change in a change set and the system
may effectively go back to the good state.
