You're right--I can now reproduce it.  I checked in (and uploaded to
the site) a fix which seems to be working:

--- submit-core.js	(revision 13062)
+++ submit-core.js	(working copy)

 var sv_end_re = new RegExp("SF:[^\r\n\t ]+?[\r\n\t ]*$");
 var sv_mult_re = new RegExp("===NEXT SERVICE FINGERPRINT");

Note that you may need to do a hard reload (shift-cntrl-r on my
Firefox) to see the change due to Javascript caching in browsers.

Cheers,
