1. emacs -Q
2. M-x customize-variable RET default-frame-alist RET
3. Custom buffer shows:

        Default Frame Alist: 
	Parameter: menu-bar-lines
	            Value: 1
	Parameter: tool-bar-lines
	            Value: 1
	   State: CHANGED outside Customize; operating on it here may be unreliable.

4. Click "State" button, select "Show Saved Lisp Expresion".  Custom
   buffer now shows:

	default-frame-alist: nil
        State: CHANGED outside Customize; operating on it here may be unreliable. (lisp)

The above just shows that Emacs sets a non-STANDARD default for
default-frame-alist.  Now comes the bug:

5. Let ~/.emacs and/or custom-file contain no setting of
   default-frame-alist. Invoke emacs (i.e. user-init-file is read).
6. Repeat step 2 above, the Custom buffer is again as in step 3.
7. Change the values of menu-bar-lines and tool-bar-lines to 0, then
   click button "Save for current session".  Custom buffer now shows:

	Default Frame Alist: 
	INS DEL Parameter: menu-bar-lines
	            Value: 0
	INS DEL Parameter: tool-bar-lines
	            Value: 0
	INS
	   State: SAVED and set.

8. Click button "Erase customizations"
   => Emacs beeps, shows message "Invalid function: (menu-bar-lines . 1)"

If in step 8 I click the button "Save for future sessions" and then
repeat steps 5 and 6, the display is as in step 7, and doing step 8
results in the same error.

If after step 6 I click "Erase customizations" without changing any
value, then the entries are flushed and the state is: STANDARD.  But
when I then repeat steps 5 and 6 again, the display is again as in 3.

I have checked a fix into the trunk that changes the way we handle
menu-bar and tool-bar lines.  The value of initial- and
default-frame-alist should now be nil, by default, at startup.
