A recipe can produce several packages. As I can see on opencv recipe, it 
can produced the following ones:

PACKAGES="opencv-staticdev opencv-dev opencv-dbg opencv-doc opencv
opencv-apps python-opencv"

and dynamic ones (depending on what else you have install)

PACKAGES_DYNAMIC="^opencv-locale-.* ^libopencv-.*"

For the opencv case, it happens that the package opencv is empty, so you 
need to append the other sub-packages it produces into your 
IMAGE_INSTALL variable.

So, it is not a bug, this is expected.
