Crash occurs in ubiquity-dm, where a dialog reports an unecoverable error, and that a live session will be started.
Started ubiqity in the live session shows a segfault.

I believe we need to cherry pick this commit from KDE Neon's fork of ubiquity.

Manually applying that change to kde_ui.py in the live session allows ubiquity to start, and complete an install.
