Profile module does not call menu_rebuild() when all items are deleted from a profile category; causes 404's on /user/%uid/edit

When you delete all the items from a profile category in profile.module, the category itself doesn't get taken out of the list of items on /user/%uid/edit until menu_rebuild() is called (by either the modules page or something else).

However, menu_rebuild() is not called by profile.module in this circumstance. I know it's a taxing function, but it should be called in this circumstance or else there will be 404's until the modules page (or something else) is loaded.
