I will first describe the problem adding a local abbrev, I suspect that
fixing that problem would also fix the flyspell problem, since flyspell
uses the local-abbrev command (at least in my setting: I have
set
(setq flyspell-use-global-abbrev-table-p nil))



Steps to reproduce (I attach the files for convenience)

    1. Start emacs -Q

    2. Load the patched abbrev.el provided by Robert

    3. Load or execute the following

       a. (setq abbrev-file-name "~/Abbrev-Doble/.abbrev-new_defs") ; or
          any other path

       b. (read-abbrev-file "~/Abbrev-Doble/.abbrev-double_defs") ; file attached

       c. (setq-default abbrev-mode t)

    4. Open a file in fundamental mode, called say new.

    5. Execute (setq local-abbrev-table (list my-abbrev-table fundamental-mode-abbrev-table))

    6. Check via edit-abbrevs (note: the properties are not displayed by
       this function! Should that be fixed also?

    7. Check whether the doble expansion works:

       a. Type a que

       b. Indeed it works

    8. Add a local (inverse) abbrev:

       a. Type nacion

       b. Put the cursor at the end of the word

       c. Type C-x a i l

       d. Type nación

       e. The error pops up
          obarray-get: Wrong type argument: vectorp, ([## 0 0 0 0 0 0 0 0 0 ...] [## 0 0 0 0 0 0 0 0 0 ...])

    9. Repeat step 7 but use C-x a i g

       a. No error! Understandable because the global abbrev table does
          not have properties.

Did I explain that enough?
