Problem for erode in python opencv

I want to erode an image with the kernel= numpy.ones(1,21,np.uint8), but the program will crash.

However I change the kernel to another value whose row value is not 1, it won't crash. Is it a bug?

Be aware of the arguments, it has to be numpy.ones( (1,21), np.uint8), this kernel works perfectly fine for me using OpenCV 2.4.8.
