This seems like an org-mode bug.  Perhaps it needs to require
outline-mode?

It does, so it is very hard to see how this error could occur.

Perhaps something had bound outline-regexp while loading stuff earlier,
leaving the variable unbound?

What is the version of org-mode?

Version: 24.3

I found one place in Emacs that might cause this (in tramp.el) and fixed it.
If it still happens to you, check to see if any local libraries might
load outline while outline-regexp is let bound.

(There are 3 places in Org that let-bind outline-regexp, but it is
impossible for any of them to cause this issue.)
