Compatibility with Crumbs?

This module is exactly what I need to diplay the complete breadcrumb in a node teaser display, to be able to track back the node location.

I use Crumbs → to manage breadcrumbs on my site, not sure if that can be the issue, but when I enable my content type and dispaly the teasers, for exmaple on a taxonomy term page, I receive the error

Notice: Undefined property: stdClass::$type in breadcrumb_extra_field_entity_view() (line 51 of /../sites/all/modules/breadcrumb_extra_field/breadcrumb_extra_field.module).

And If I go to the standard node view the <div class="field breadcrumb-extra-field"></div> is empty.

Update

The issue has two components:

1. Notice: Undefined property: stdClass::$type. This has moved to #2932583: Some entity types don't have a ->type property. →
2. Compatibility with Crumbs. This is discussed here.
