ubi-partman crashed when choosing guided encrypted LVM installation

[Rick Scholten]

In the Kubuntu installer I choose guided encrypted LVM install and after clicking "Install Now" ubi-partman crashes with exit code 141.

Choosing "Guided - use entire disk" does work without a problem.

This appears to be the result of the recent Ubiquity FFe adding "Master recovery key"
