REVISION SUMMARY
  This fixes a race condition on startup for the Kirigami translation
  catalog that happens as follows:
  
  - QML code triggers the loading of the Kirigami plugin
  - the ECM QM loader is triggered, but since this is running outside of the
  
  main thread, the actual QM loading is deferred to the main thread
  
  - QML code execution continues, at which point qsTr might still return
  
  unstranslated strings
  
  This is for example visible by the "Actions" header in the context drawer
  of the main application page not getting translated.

  R169 Kirigami
