I'm seeing a bug when calling `MagickAdaptiveBlurImageChannel(magickwand, 5, 1, BlueChannel);`

Output Image
Running the code through valgrind reports lots of reads from uninitialised memory. Running an equivalent command through convert shows similar errors in valgrind. The image generated through the command line varies, and does not appear to be always correct but is not as dramatically wrong.

convert magick:logo test.png
valgrind convert test.png -channel B -adaptive-blur 5x1 output.png
