Hi Uwe,
Ive now had some time to look into this further. Below are the error messages I received.

When in release mode, the QT console returns:
Qt Code: 
  1. convertHIconToPixmap(), failed to GetIconInfo()
  2. QPixmap::fromWinHBITMAP(), failed to get bitmap info (The handle is invalid.)
  3. QPixmap::fromWinHBITMAP(), failed to get bitmap info (The handle is invalid.)

When in debug mode I get:
Qt Code: 
  1. Program exited with code 03.
  2. (gdb) 
  3. QFSFileEngine::open: No file name specified
  4. convertHIconToPixmap(), failed to GetIconInfo()
  5. QPixmap::fromWinHBITMAP(), failed to get bitmap info (The handle is invalid.)
  6. QPixmap::fromWinHBITMAP(), failed to get bitmap info (The handle is invalid.)
  7. ASSERT: "m_hdc" in file painting\qpaintengine_raster.cpp, line 4286
