@Daniel I see your point about Mir. Anyway, all I'm saying is this
problem manifested via
https://errors.ubuntu.com/problem/bcb050f97778eb836056c1c48139bcde30ed0bcb
is completely different from the original problem described in this bug.
The only common thing is qFatal() gets called. In the original problem
it was called directly by unity8-dash in response to boost throwing
exception on incorrect locale (which was fixed by the attached MP). In
this new case this is something else in the stack calling qFatal and
aborting unity8-dash and I see no evidence of locale being involved.

To sum it up, I think it's a different bug and I don't think unity-
scopes-shell (the dash) or unity-scopes-api are responsible for this.

Title:
  unity8-dash crashed with SIGABRT in qt_message_fatal() under incorrect
  locale

Status in Canonical System Image:
  Confirmed
Status in unity-scopes-api package in Ubuntu:
  Confirmed
Status in unity-scopes-shell package in Ubuntu:
  Fix Released

Bug description:
  unity8-dash gets into a respawn loop when the selected locale is
  unavailable. While it's understood that incorrect locale might result
  in unexpected behaviour, but aborting feels excessive.
