 What most likely is happening is that you have an unbalanced paren
in
 there somewhere.  Mule can do this to you if you have Japanese strings
 encoded in 7-bit JIS in your .emacs but for some reason isn't
 recognizing it correctly.  I don't know if SJIS can do it. 
 There's probably a better way, ... 
xemacs --debug-init.
This is documented in numerous places.
