GreyBones,

I don't recompile OpenCV and Gphoto2 to kill this crash. I just apply my
previous patch, used offical OpenCV and Gphoto2 from Mandriva repository
(OpenCV compiled with libdc1394 support), and now digiKam do not crash when
Gphoto2 API is called.

Note : at startup, i can see that digiKam try to init libdc1394 now, which
prevent conflict between OpenCV and Gphoto2 :

... look the first line at startup. You must see the same. My patch just link
digiKam with libusb when Gphoto2 support is enabled. OpenCV is always used with
digiKam 2.0.0, for face detection support (it's not optional)
