I just had this problem in a mode I'm writing.  I found that
it occurs when local-abbrev-table is not set.
local-abbrev-table is buffer local when set but if it's not
set the default is usually fundamental-mode.

What version of Emacs doesn't set local-abbrev-table?  If I run
emacs-21.3 -q --no-site-file -f sh-mode, `C-h f local-abbrev-table'
displays

And `M-: (eq local-abbrev-table (default-value 'local-abbrev-table))'
returns nil.

I guess the workaround for OP is something like:

(add-hook 'sh-mode-hook
           (lambda ()
             (or local-abbrev-table
                 (setq local-abbrev-table (make-abbrev-table)))))

It might just be an unwanted side effect of something in OP's .emacs.
For example I saw the code below on emacswiki.  It would cause these
symptoms and a user may not connect the two without understanding the
connection between add-mode-abbrev and local-abbrev-table.

(defun sql-pre-abbrev-expand-hook ()
  ;; Allow our abbrevs only in a code context.
  (setq local-abbrev-table
	(if (sql-in-code-context-p)
	    sql-mode-abbrev-table)))

add-mode-abbrev writes to fundamental table only

[Harry Putnam]

Emacs version (yesterday cvs)

If this isn't a new problem related to cvs emacs then it might be a
good subject here:

I'm finding when I have entered any mode (Here we use sh-mode) that
running `add-mode-abbrev' will only write my new abbrev to the
Fundamental-mode-abbrev-table.

Test by:

C-x C-f some.sh <RET>
M-: major-mode<RET>
(Verify it is sh-mode)
newab<M-x add-mode-abbrev><RET>nb<RET>

Now M-x edit-abbrevs<RET> and search for newab.  See what abbrev table
its under.

This is a hefty overstatement  (any mode) it should have said only
sh-mode, as it seem to be confined to that mode only.
