Deadlock when removing qml profiler dock widget from parent window

    XMLWordPrintable

Details

    Description

      1. Open the QML profiler by clicking on analyze, make sure you see the timeline view.
      2. Right click somewhere in the menus of the qml profiler.
      3. Uncheck "locked" => the little button allowing you to detach the window appears
      4. Click on that button.

      The application hangs. The backtrace shows that multiple threads are waiting for each other:
