Do you have a recipe?  It should not signal an error, and I can't 
reproduce that.  With this for instance:

M-: (global-set-key (kbd "C-t") (lambda () (interactive) (with-restriction 20 30 (message "{%s}" (buffer-string))))) RET

C-t (in *scratch*) displays {or text th}, even if the text is narrowed say 
to the second line.
