|I don't understand where the following warning is coming from:

Because you skipped the "initialize" of Exception.  You have to call
"super" in your version of "initialize".  I'm still not sure you will
get what you want.

The behavior differs in 1.7;  It will not give you warning.

1.6 without super

  ruby 1.6.7 (2002-03-19) [i386-linux]

1.6 with super
