There is absolutely no constraint about labels in KnpMenu. But while working on #45, I figured that the label is used as key in the return value of getBreadcrumbsArray, meaning the method is totally broken when a label is used twice in a path in the tree.
Fixing it would require a BC break as the bug comes from the design chosen for the method (which still comes from ioMenuPlugin)
