Unfortunately this all has do do with a dll library from a camera, which 
would not work on linux.

If I compile with msvc-2005 instead I experience the crash in the 
destructor of the vendor header file
loading the dll (at line '_scamlib = NULL;' )

   void Shutdown() {
       // unload the library
       if (m_scamlib != NULL) {
           ResetFunctions();
           ::FreeLibrary(m_scamlib);
           m_scamlib = NULL;
       }
   }

Now since it all only appeared if the camera dll was loaded I replaced 
all the dll loading functions
(basically I replaced most of the vendor header file) with a class 
replacing the functions using QLibrary.
Now I do not experience any crashes.

Nevertheless - I still do not understand why it crashed.
