Oh boy!
TIFF is a tag interface format and any one of the tags can be bad to give you this error.
Also some of the tags could be incompatible with your system..... 
for instance:
    superpaint will read in a tiff file but only if it's a one bit deep bit map (ie. black and white)
    if you try a 8-bit or 4 bit-grey bitmap the Superpaint chokes. and puts up some
    error message. Some programs (Pagemaker, I believe) will ignore some incompatible fields
    ie. you designate the length of the bitmap as 0 instead of the correct size. (this happened to me) 
    Pagemaker displays the image and some garbage that is at the end of the file.  

However, Not having the NeXt tiff images I cannot decode and find the exact problem in them
so sorry.
