Paper UI REST call to /thing-types hangs for a certain Thing

My paper ui control page was blank and I tracked it down via dev tools to this call not completing.

curl '' -H 'Accept: application/json, text/plain, */*' -H 'Referer:' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.74 Safari/537.36' --compressed

It just hangs, never finishes. Not sure how the interface handles this but this item caused the control page not to load at all. Removing this thing fixed it but that’s a temp solution as I want it. :slight_smile:
