Re: flyspell bug

[Richard Stallman]

    To avoid such failure, ispell.el could check the Aspell's exit code
    and in case when Aspell can't find a dictionary name among its list
    of available dictionaries, ispell.el could change the default program
    name from "aspell" to "ispell" and try to run Ispell with the same
    dictionary name.

That is an ugly temporary workaround.  What I would rather do is give
a clear error message that points the user at the ways to reconfigure.
