Yes, this example works in 4.3MR6a, as well.

I fixed all of my regions to have explicit names and was still having
the problem.  Cutting the FO file down to just the page sequence I was
trying to get working made the error disappear, so I gradually added
the rest of the content back, finding in the process that my "blank
page" simple-page-master was actually getting used at the end of the
file for a page with just the words "End of Book" on it.

It was this attempt to put content on the page I was trying to make
unable to hold content that was triggering the error.  Since the
page-master was being used directly, the formatter did not have the
option of generating further pages in the sequence until it found one
that could accept the content.  Changing the fo:flow to explicitly
place its content into my "blank" region resolved the problem.

Well, you know... "think outside the box... er, margins!" :)

Thanks again for pointing me in the right direction!
