It's a bit hard to tell without knowing what version of Aquamacs  
you're using, and which customizations are in effect.
Do you have track-eol set to `t' ?

If so, the patch below might help; but I then again, the error message  
doesn't quite match.
(Don't forget to byte-compile or remove visual-line.elc after applying  
the patch.)
