When I eval revision 6.11.2.2 of rfc2231.el (evaluation the defun
`rfc2231-parse-string' is sufficient) everything is displayed fine:

,----
| [2. message/external-body; test-file-2.txt]...

When I eval revision 6.11.2.4 (latest revision in v5-10 branch) of
rfc2231.el, I get:

,----
| [2. message/external-body; us-ascii''%2ftmp%2fste%2fgnus%2fattachment-external-body-test-directory%2ftest-file-2.txt]...

Bye, Reiner.
