The OP: a) hasn't replied; b) did not mention summaries at all; and c)
said this was "fairly recent" behaviour; whereas the issue identified
occurs since 23.1, but only when summaries are present.

Nevertheless, I think you probably identified the problem, and I
committed a fix.

Summary:

emacs -Q
C-u M-x rmail RET ~/xmail RET   ; non-empty folder
h
C-x 1 
C-u M-x rmail RET ~/RMAIL RET  ; non-empty folder
o RET    ; output message from RMAIL to xmail

At this point, xmail buffers appear.
