bug#44318: 28.0.50; Problem with ispell/flyspell and ""enchant"" backend

[dinkonin]

Hello,
I'm having some trouble with flyspell using the enchant backend
(setq ispell-program-name "enchant-2").

I have installed the latest enchant 2.2.12, without the
optional finish and hebrew backends. Flyspell refuses to work with the
above setting (no errors just does not detect anything ). Ive
narrowed it down to this:

when flyspell loads it adds the following line n top of "ispell-enchant-dictionary-alist"

((nil "[[:alpha:]]" "[^[:alpha:]]" "[\n** (process:98935): WARNING **:
22:05:56.283: Error loading plugin: libvoikko.so.1: cannot open shared
object file: No such file or directory\n\n\n** (process:98935): WARNING
**: 22:05:56.286: Error loading plugin: libhspell.so.0: cannot open
shared object file: No such file or directory\n\n0123456789]" t nil nil
utf-8)

The problem disappears when I manually do:
(setq ispell-enchant-dictionary-alist
      '(("bg_BG" "[[:alpha:]]" "[^[:alpha:]]" "" t nil nil utf-8)
        ("en_US" "[[:alpha:]]" "[^[:alpha:]]" "" t nil nil utf-8)))
                                         
I've noticed that enchant-lsmod-2 also produces this error in the
terminal, maybe STDERR should be omitted when generating
ispell-enchant-dictionary-alist or shoud this be reported upstream to
enchant ?
