These are normal.  When something goes wrong, options show up this way
because the customization interface doesn't see a nice way to format and
edit them reliably.

Call `customize-rogue' for a list of options where customizing fails the
same way with emacs -Q.  It's a nasty habit of programmers to ignore the
customization interface.
