Fluxbox.

First I get a backtrace.  Sigh.

Debugger entered--Lisp error: (wrong-type-argument keymapp nil)
  signal(wrong-type-argument (keymapp nil))
  define-key-after(nil [customize] (menu-item "customize" customize :image 
(image :type xpm :file 
"/usr/local/emacs-21/share/emacs/21.3.50/lisp/toolbar/preferences.xpm") :help 
"Edit preferences (customize)"))
  tool-bar-local-item("preferences" customize customize nil :help "Edit 
preferences (customize)")
  apply(tool-bar-local-item "preferences" customize customize nil (:help "Edit 
preferences (customize)"))
  tool-bar-add-item("preferences" customize customize :help "Edit preferences 
(customize)")
  tool-bar-setup()
  tool-bar-mode(toggle)
  call-interactively(tool-bar-mode)
  execute-extended-command(nil)
  call-interactively(execute-extended-command)

Then the frame gets oversized (namely, the text window size does not
shrink to accommodate the toolbar size, and consequently the
minibuffer gets off-screen).  If I disable the toolbar again, the
frame shrinks to normal size again, as the window size stays the same.
However, this first toggling is "neutral" only because of the back
trace, apparently (I have debug-on-error set to t).

The next time I call tool-bar-mode (no backtrace this time), the
window-size _adapts_ to the reduced space.  Disabling tool-bar-mode
again, the window does _not_ adapt to the additional space again.

After that, enabling the toolbar makes the size adapt, so the frame
size stays more or less the same while the window size shrinks, and
disabling the toolbar lets the window size stay the same, thus causing
the frame to shrink.

The same happens when detaching and reattaching the toolbar: detach
the toolbar, and the window does not grow in spite of the additional
space, attach it again, and the window shrinks.

Maybe this is an effect of the combination of my line height and the
size of the toolbar?  I use 10x20 as my normal font, and the startup
geometry is 80x35.

My X resources contain Emacs.toolBar: 0, so I don't have a toolbar on
startup normally.
