Qt Creator : Debugging sessions doesn't start

[daudrain]

Today I've been able to debug a small test application, set breakpoints and trace the code.

However it does not work so well with a bigger application (SIS is 1630ko large), Qt Creator logs the following :

Deploying application to 'Nokia N8-00 USB Serial Port (COM6)'...
Copying installation file...
Installing application...
Launching debugger...

And the application doesn't show up on the device. (It does show up if I launch it myself.)

Any idea what could prevent my application to start when starting a debugging session?

Removing Phonon objects creation solved the issue.
