Well, Nautilus and gThumb certainly share thumbnails (I just checked), 
so it should work for you.

There is no additional thumbnail info stored outside of ~/.thumbnails.

I would run exiftool against one of your thumbnails, and compare the 
results to those of Nautilus's thumbnails. Compare the thumbnail size, 
image type (RGB, 8 bit), mtime, exact URI encoding, and permissions.
