[plt-scheme] PSD problem

Greetings,

I am attempting to use PSD 1.2.1 with GNU Emacs 21.1
and MzScheme 103 under Windows 2000.  When attempt
to use it I get:

The ^U Esc ^X works but when I try to add a break point with
^X Space I get:

Wrong type argument: sequencep, 6

in the Emacs mini-buffer.  The "6" seems to correspond to the
line number I am attempting to break.  Of course I have the cursor
in the source file when I attempt the ^X Space.

I appreciate any help you can offer.
