Problem when deploying the app with sending SMS & play video functions into real device N900.

In our "DestineVietnam" app, we include the new Qt Mobility 1.0.0 and use the functions like sending SMS, playing video.
When we build the app for Maemo and try to deploy it into real device, we got serious problem.
We did try two ways of deploying:
a) Deploy the project direct from Qt Creator: it crashed and the Qt Creator is closed (pls. see the attached picture for more detail)
b) Build the project by command line (via MADDE terminal ) and deploy the .DEB file to N900 : the app cannot run and the device is stop working
