Local Ispell dictionary set to nil

[Klaus Zeitler <kzeitler@lucent.com>]

as of recently emacs prints the message "Local Ispell dictionary set to nil",
when I load a new file (that uses flyspell-prog-mode).

I think it has something to do with the fact that flyspell calls
ispell-change-dictionary with the following parameter
 (or ispell-local-dictionary ispell-dictionary flyspell-default-dictionary)
that evaluates (and has before) in my case to nil.
I glanced at the source code of ispell-change-dictionary and it looks to me
as if this function handles "" as default dictionary but not nil.

a knob called `brightness', but it doesn't work.          -- Gallagher
