System Error when running Ganache 2.1.0 on darwin ('pop' of undefined)

Got this crash error, maybe related to gas estimation by metamask + remiz
PLATFORM: darwin
GANACHE VERSION: 2.1.0

EXCEPTION:

I don't think this is related to gas estimation, as I got the same error on the same line just on starting up Ganache immediately after selecting the Quickstart workspace. (Notes at #1320).
