My suggestion is to catch the shutdown itself.  That should go through
kill-emacs, so a breakpoint there should be enough.  If you want to be
more sure, set a breakpoint on 'exit' and 'abort' (2 library
functions).  Then run Emacs and use it as usual.  When these
breakpoints break, a backtrace should tell us what is going on.
