This probably won't be much help, but occasionally I've noticed unusual
problems with keybindings in Emacs where a key seems to be bound to more
than one command.  You might try checking "C-h k <M-up>" and see what it
says.

Also, try with "emacs -q" and "emacs -Q" and see if you can reproduce it
that way.  That might help narrow it down.
