If miral-shell is part of your workflow...it broke

[Alan Griffiths]

Guys,

On the latest Zesty archive miral-shell has been broken by a standard
library update. (https://bugs.launchpad.net/miral/+bug/1677550)

This exposed a latent bug in the default window manager which now
crashes on startup. (Using miral-kiosk or  'miral-shell --window-manager
tiling' avoids the problem).

There's a fix in silo 2676 awaiting QA (and will hopefully land sometime
soon).

Sorry for the inconvenience,

Alan
