crash when debugging app

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-

).
