      Using Qt.inputMethod.visible in QML application causes it to freeze. If I remove line 27 from deadlock.qml no freeze anymore.

      Steps:
      1. Tap input field.
      2. Write some.
      3. Press enter on VKB.
      4. Repeat 1-3 until application freezes (some times it might take a while)

      Expected: No freezing
      Actual: Application freezes and when user tries to regain focus to TextInput application log says :
      I/dalvikvm(24430): threadid=3: reacting to signal 3
      I/dalvikvm(24430): Wrote stack traces to '/data/anr/traces.txt' (attached traces)
