Ok, there were a couple of bugs because I thought mxacts wouldn't need
to be supported. So far your testcase doesn't crash the database
anymore - it spews some internal errors though, so I am not sure if it's
entirely fixed for you.
Thanks for testing and helping!
I've pushed the changes to the git tree, they aren't squashed yet and
there's some further outstanding stuff, so I won't repost the series yet.
