Yikes!  Why do you insist on formatting Lisp code as if it were C or
(God forbid) Pascal?  It makes it very hard to read and comprehend.

Well, is your function at all called?  Does the message you produce at
the beginning of your function gets inserted into the *Messages*
buffer?

In other words, the first question you should answer is: is the
signal delivered to Emacs and handled, but your function has a bug,
or is the signal itself handled incorrectly by Emacs?

And it will help immensely if you tell what version of Emacs is that
and on what platform.
