Distributed application crashes instantly, development version works fine.

Hi! I must be missing something because for some reason my application crashes instantly when opened. Tried both OSX and Windows, and crashes just after opening the main window.

The development version (tested on OSX) works fine, works on both release and debug mode. If I add the frameworks inside the app, it crashes when opened, If I don't, works fine, but I can't open it in other computers without Qt.

I have tried also on windows and is happening the same, if I try to open it delivering with its dll's, when I open it it will crash instantly.

the app is using qtcore, qtgui and qtopengl.

What does the debugger say? Where does the crash occur?
