    Description

      I am attempting to use qtcreator to debug a QML application that imports both shared libraries and qml installed on the host.

      I run the app with 'qmlviewer main.qml' in the relevant directory and it works fine.
      I can run it from without qtcreator using the Run button and it runs fine.
      However, if I run it with the 'Start Debugging' button, it will crash.

      There are a set of steps to do to make it crash, but it seems quite reliable.

      The dialog says :

      "
      The inferior stopped because it received a signal from the Operating System.

      Signal name :
      SIGSEGV
      Signal meaning :
      Segmentation fault
      "

      If I also enable 'C++' in the 'Debugger' settings of the 'Projects' settings, then I also get a backtrace and that points to code in the QDeclarativeDebugServer...actually, the top of the stack is 'QObject::objectName() const'

      I have enabled the Debugger log view and attached the output.

      The application is the widgetgallery in meegolabs-ux-components, but there's some set up required (mainly installing the latest git for meego-ux-

      {components,media}

      ).
