actually the return array of getBreadCrumbs() contains the link and the title. It should also contain the menulink title.
On the one side it would make the breadcrumbs more consistant. The menutitle should be available in all parts of menus, and the breadcrumb are a part of this.
The other reason is, that the page title sometimes is really long, because is contains a lot of additional infos to the menutitle. This makes the breadcrumbs extrem long. It would make sense to have the menutitle as possible value in the breadcrumb result to be more flexible.
