Title:
  Need to use QMirServerApplication, The program has unexpectedly
  finished.

Status in The Unity 8 shell:
  New
Status in unity8 package in Ubuntu:
  Confirmed

Bug description:
  I just installed my new PC with everything including the SDK according
  to the following website:

  http://developer.ubuntu.com/start/ubuntu-sdk/installing-the-sdk/

  The I got the following tutorial codes at:

  bzr branch lp:ubuntu-sdk-tutorials

  When I am trying to run the "scope" sample app, the Qt creator gives
  the following error:

  
  Starting /usr/bin/unity-scope-tool...
  scoperegistry: no remote registry configured, only local scopes will be available
  RegistryObject::ScopeProcess::exec(): Process for scope: "openclipart-scope" started
  TabBar model must have selectedIndex property defined.

  Need to use QMirServerApplication
  The program has unexpectedly finished.
  /usr/bin/unity-scope-tool crashed

  
  Finally, I figured it out that the error was related to the missing installation component " unity8-fake-env ". After I have installed it, it is fine. The same kind of bug was reported at https://bugs.launchpad.net/ubuntu/+source/unity8/+bug/1306343. My question why  "unity8-fake-env" is installed in the first place when the SDK is installed.

  Thanks & best regards,
  xiaoguo
