Coder Error Reading TIFF Image with Group 4 Compression

Reading TIFF CCITT Group 4 (scanned or faxed) images with MagickImage in C# throws MagickCoderErrorException. The exception message is shown below:
Magick:: Null count for "Tag 32934" (type 4, writecount -3, passcount 1).
'_TIFFVSetField' @ error/tiff.c/TIFFErrors/563

If the TIFF image is decompressed first, then the reading works fine. Anyone came across this error before and any suggestions on how to resolve this?

Thanks,
Sam

It is better to ask question related to Magick.NET here: https://magick.codeplex.com/discussions. Can you include a good and a bad image in your post there? And a code example?
