OK so trying this:
``` name: try-kiosk-x11 version: none summary: Segfault on stage-snaps description: | This shows snapcraft segfaulting on stage-snaps confinement: strict base: core18
parts: mir-kiosk: plugin: nil stage-snaps: - mir-kiosk-x11 ```
Fails as expected, because mir-kiosk-x11 is core20-based. But changing it to `/latest/beta` and rebuilding without cleaning will segfault again. After clean, it works correctly.
