This is now fixed in the emacs-26 branch.

Change this regexp in ispell.el:

  "(but really Aspell \\([0-9]+\\.[0-9\\.-]+\\)?)"

into this:

  "(but really Aspell \\([0-9]+\\.[0-9.]+\\([-._+ ]?[a-zA-Z0-9]+\\)?\\)?)"

Then byte-compile ispell.el to produce a modified ispell.elc, restart
Emacs if it's running, and you should be all set.

I'd be interested to know whether this fix makes the problem go away
for you.
