I noticed this problem too.  I reported the following concise recipe for
showing it, but I never heard that it has been fixed (which is normally
what happens)...  It's a really irritating bug that bites most of the time
when I move around an RMAIL buffer.  I hope it has been fixed!

In GNU Emacs 19.27.1 (sparc-sun-sunos4.1.3C, X toolkit) of Thu Sep 15 1994 on penelope

Motion commands when you have a summary buffer appear to skip messages
that they shouldn't.

% yow | mail me
% emacs -q

M-x rmail RET h C-x o

RMAIL's modeline shows (1/1).

% yow | mail me
% yow | mail me
% yow | mail me

Type `g' (RMAIL's modeline shows (2/4)),
then `d' (RMAIL's modeline shows (4/4)).

You have skipped to the third (last) new message, rather than the
second new message.

Note if you stay in the RMAIL-summary buffer (i.e., do not C-x o), you
also get a bug when reading the 3 new messages:

Type `g'.  The fourth mail item is shown as read (the RMAIL-summary buffer
line for message 4 does not contain `-').
