I noticed that I have similar queries that work as expected. The difference appears to be
that every query that is broken uses " WITH ROLLUP", and removing this makes them behave
as expected.

Is this a known bug? Should I submit it as such?

If someone would be so kind as to point me to the bug system, I'll crawl around in there
to see if it's a known problem.

There is a bug that I about a half year ago reported,
http://bugs.mysql.com/bug.php?id=68564, that the NULL one expects with "WITH ROLLUP" is
not always NULL, but is instead the foregoing string in the same field. I suspect that
other bugs with missing NULL found by searching for ROLLUP are the same problem. (note
link titled "Affects Me"!)

Another, one year ago reported, bug of mine was handled in 5.7.2, but this one not.
