My first impression is that you are using aspell and fr_CH locale
and did not explicitely select any dict (and have no aspell
fr_CH dict available). What happens if you explicitely select
a dict by means of ispell-change-dictionary?

and also have no aspell english dict installed. Probably a reasonable
fallback should be added for default in case an english dict is not
available. Does the problem persist if you have an aspell english dict
installed?

Which one is the surprise? Note that for emacs-cvs ispell.el, if aspell
is installed it is the default, even if it has no dictionaries available
for the desired language. You will need to explicitely set
ispell-program-name to ispell if you want it.

Hope this helps
