Are you multithreaded? I had a similar (non-Qt) problem due to an  
initialization race condition in my code. These types of bugs are easy  
to create when you mix statics, DLLs and threads, and the order of  
initialization is not deterministic, which may be the case if multiple  
threads are running before DLLs get loaded.
