OK, I see that as well.

No.  I fixed this now on the emacs-24 branch (r116902).

(For he record, this crash didn't happen on my system because there
bidi_initialize is called for the first time before the user init file
is read, and therefore force-load-messages is still nil.)

You can call Ffeaturep, since each of the *.el files by convention
provides a feature unique to that file.

Yes, it's normal, see display_menu_bar in xdisp.c, for example.

Thanks.
