 For the code
 {{{
 (ql:quickload :rfc2388)
 (RFC2388:PARSE-HEADER "multipart/form-data;
 boundary=------------------------ea3255a8d6193fb7" :VALUE)
 }}}

 there is surprisingly no error returned to SLIME.

 Running ABCL from the command line returns the following trace

 }}}

 Two problems:

 1) Why does SLIME not catch this error?

 2) Figuring out what is the problem with the underlying code
