You might need 'scm-error' instead:

(scm-error 'misc-error 'the-procedure-name "foo ~a" '("args") '())

The documentation in the manual is a bit confusing -- as 'scm-error' is 
mentioned right after 'error', you might easily read "message 
constructed by displaying msg and writing arg" as "it displays and 
writes using 'format' on msg and the arg ...". Some room for improvement 
there.
