I agree with Stefan that the current order of calling a hook and
setting local variables (either dired-local or file-local) is wrong.

Another problem with the current order is that it is impossible to use
`bug-reference-mode' on ChangeLog files.  We already have a local variable
`bug-reference-url-format' set in Local Variables to the string
(BTW, this file-local variable should be moved to .dir-locals.el)

And when I try to enable `bug-reference-mode' using the following hook:

  (add-hook 'change-log-mode-hook 'bug-reference-mode)

it never gets enabled because `bug-reference-mode' tests whether
a variable `bug-reference-url-format' is non-nil before enabling this mode,
and this variable is not yet set because it gets initialized later in
