    I'd like to give you a bigger stack trace but it appears to only give me this:

    face_detect.rb:15: warning: OpenCV error code (-206) : cvGetMat (2882 in cxarray.cpp)
    face_detect.rb:15:in `detect_objects': Unrecognized or unsupported array type (OpenCV::CvStatusBadFlag)
    from face_detect.rb:15

    What I can tell you is that the application starts and shows a white box on the desktop, and the green light for the isight becomes active. However, nothing happens until I press a key. Once I do press any key I get that error.

    Is that helpful at all? Do you know how I can produce a proper stack trace for you?

    Thanks for trying to help!
