EntityMalformedException: Missing bundle property on entity of type node in entity_extract_ids()

We're seeing the same problem. With Biblio 7.x-1.3, we see the same error when trying to add a node:

LOCATION https://web.url/node/add/biblio
REFERRER https://web.url/node/add/biblio
MESSAGE EntityMalformedException: Missing bundle property on entity of type node. in entity_extract_ids() (line 8003 of /drupalroot/includes/common.inc).

Rolling back to 7.x-1.2 fixed the problem.

Please use git bisect to figure out which commit caused this problem.

It has to do with this git commit hash 9a284d1 for the issue #3088436: Undefined function search_index() on node save when core search module is not enabled. The biblio index node internal function added a check if the operation is an update, but didn't moved the _node_index_node($mynode) into the if logic.
Did some quick testing with a known site that was not working and this seems to get it back to a working state.

As a temporary work around just disabling the indexing of biblio items when creating/updating, add all your new items. Then you can renable the auto indexing on creating/updating as the update operation does work with this code.

Turns out I missed when new biblio's are created the index of the new node was not added into the search. This should fix that.

Thanks!
