I can't say if you are doing wrong (command syntax looks fine) without 
an image file to look at.  Maybe there is a bug.  Is it possible for 
you to provide me with one of the problem images to look at?

Did you build GraphicsMagick yourself?  Does your build use 16 bit 
quantum depth, or the default 8 bit quantum depth?

Yes.  I fixed that in the CVS version shortly after 1.1.3 was 
released.
