bug#7032: 24.0.50; customize can crash emacs

[Joseph Brenner]

I've got some problems with latest build of bzr emacs.

In trying to use custom.el to make a change, I repeatedly crashed
emacs by doing this:

  MH-E => mh-variant => Gnu mailutils
    "Save for future sessions"

I tried this several times before I finally got it to save successfully.

  (custom-set-variables
   [...]
   '(mh-variant "GNU Mailutils 1.2")

I believe I got it to work by deleting this line from my .emacs,
it had somehow gotten placed below the custom-* code:

  (put 'scroll-left 'disabled nil)

Sorry, I don't have a -Q recipie or a gdb trace.
