Public bug reported:
Upgraded from 18.04 to 19.04 (then 19.10 last week in Paris).
Had a few desktop shell lockups. Pattern seems to be when running snap
refresh, but this time happened when running snapcraft --use-lxd. Feels
like something related to mounting / unmounting devices. Got this from
the journal.
