App crash when using betatesting.ane on iOS5

Hello,

I use the Testflight ANE provided in the last Adobe Gaming SDK (1.3)
No problem on iOS7 but my app crash on iOS6 when instanciating TestFlight.

Edit : Crash appends on iOS5

var testflight:TestFlight = new TestFlight(key, false);

-> App runs well when i comment this line...
