After 7.5.0.GA release it is not possible to launch a Titanium app through an intent. It hangs on the startup.
It seems related with new safeArea feature implemented on 7.5.0 SDK. Why is happening this? I don't know but it should not influence in the communication between apps.
I've attached a sample app and the logcat error trace.
Steps to reproduce:
1. Compile both apps and deploy it.
2. Launch SourceApp
3. Click "Open Target"
4. TargetApp hangs at startup due to Ti exception
