"Cannot create thumbnail" - Tame/2 / SANE create a TIFF, but no TN Options

[Guest_Al Savage_*]

I am doing some testing of the upcoming Tame/2 GA release, and I found that it can create a TIFF file that my old (beta) version of PMV says can't create thumbnail.

The subject file is 64MB, so I can't just post it for review, and I have a 26.4k connection to the world

Is there a method to determine, on my end, why PMV cannot create a thumbnail.

Naturally, PMV opens and displays the file OK.
