The original error is gone but now I'm seeing something very, very  
strange, as shown in the screenshot:  the wrong images show up in my  
header line.
The header line image is this:

(image :type png :file "/Users/dr/ae.git/nextstep/Aquamacs.app/ 
Contents/Resources/site-lisp/tabbar/close-tab.png" :ascent  
center :margin 0))

and it switched to the wrong image just after I did C-c C-x C-l for  
teh second time.

In fact, I then notice that ALL images are replaced with the "redo"  
image.
Now that shouldn't be...

Also, it tells me to press C-c C-c to remove the images (which aren't  
there), and when I try this, it tells me that nothing useful can be  
done at this point.   Maybe that's intended, since the image isn't  
shown.

(This is with Aquamacs/Cocoa, a branch synced with Emacs 23, but that  
shouldn't make a difference.)
