Changing the value for core to "simple" is not a workaround because it renders the performance non-functional.
It got fixed in Debian in version 0.74-4-3, which means that this package has been broken in Ubuntu for a year and a half, or three consecutive releases. It first made its appearance in Bionic which is as of yet unreleased, but the Bionic version immediately fixes the performance issues (and otherwise crashes) and is installable without any extra dependencies on Yakkety, Zesty and Artful.
