Title:
  MIR refuses the app to connect

Status in Autopilot:
  Incomplete
Status in unity-mir package in Ubuntu:
  New

Bug description:
  When running several camera-app tests in a sequence, randomly we have the application crash.
  Tracing the crash leads to a fatal error in qtubuntu when trying to connect to MIR. The stack trace follows below.

  According to elopio this might be because the app has not exited yet from the previous tests when running the next one.
  I am attaching the AP log as well.
