pickContact crashes when linked contact selected

Picking contacts works for many contacts, but for certain contacts it crashes every time with the following error:
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'A contact and its snapshot should both be non-unified.'

My guess is that this is due to the problem contacts being "linked". This article suggests that is the cause:

Just a note, when I enter: "cordova -v" it tells me I have 5.3.3, but that option was not available in the "Affects Version" field, so I just selected 5.3.2.
I installed cordova-plugin-contacts today, so it's the latest.
