FeaturesDetector and DescriptorExtractor returns a null pointer (opencv 2.4.9) (Bug #2280)

When you run the following code, cv::DescriptorExtractor::сreate and cv::FeatureDetector::create return a pointer to NULL, but it is not an throw exception. Library version OpenCV 2.4.9. On older versions of the library code works correctly.
