Qtcreator 2.6 harmattan

[rferrazz]

When i deploy an application from qtcreator 2.6 it runs on the device (N9) but when i try to launch the same application from the device itself (tapping the icon) it won't start, the log message is:
@
Dec 14 17:57:17 (2012) applauncherd[5665]: Booster: Loading invoked application failed: '/opt/WebDomoN9/bin/WebDomoN9: cannot dynamically load executable'
Dec 14 17:57:17 (2012) applauncherd[866]: Boosted process (pid=5665) exited with status 0

I've setted up the kit in this way:
target: harmattan
device type: meego1.2 harmattan
compiler: /opt/QtSDK/Madde/targets/harmattan_10.2011.34-1_rt1.2/bin/gcc
qt version: /opt/QtSDK/Madde/targets/harmattan_10.2011.34-1_rt1.2/bin/qmake

Can someone help me?
Thanks!
