I hope that's just a joke, and no more.  I think we should create a testsuite
to help stop such regressions.  This is difficult, of course, with a GUI
application but here's a suggestion for one approach:

Arrange for error to print to standard error when Emacs is run
non-interactively (actually I think it already does this).  Then for each bug
report that results in a Lisp error, we create a Lisp test file to reproduce
the conditions that generated it, put it in a directory called testsuite and
create a Makefile where:

make test

will run:

emacs --batch -l testxy.el

for each test file in the directory.

and check for output on standard error (I don't know how to do this in a
Makefile or from sh.

Currently I get some messages, e.g.,
"Loading /usr/share/emacs/site-lisp/site-start.d/..." on standard error but
I'm not sure why.
