Locator stays open while triggered action freezes GUI

1. Open a file from Creator's repository.
2. Type "t pull" into the Locator bar and press Enter.
   I don't think this matters, but I enabled "Pull with rebase". Creator's GUI freezes until pulling finished. That is QTCREATORBUG-19889, but this report is about something else:
   The Locator window will not close while the GUI is frozen. In this time it is unclear whether the action was triggered or not.

The Locator window should be closed before actually triggering the action. Then the Locator window would not stay open all the time while the triggered action might freeze the GUI.
