Cameras can do all kinds of things with image data, but I can't think of any
software that'd honor a "do not resize this image" setting even if it were
set.

Find out what the problem is by doing "identify -verbose NON_THUMB.jpg >
nonthumb.txt ; identify -verbose THUMB.jpg > thumb.txt" and then looking at
the first hundred lines of output in both files. Then play "one of these
things is not like the other". The problem should become obvious.
A while back, someone sent us a JPEG at work. This image would render just
fine in Safari and Firefox, but wouldn't display anything in IE. The problem?
Its color profile was CMYK, not RGB. *sigh*. Your problem may be similar.
HTH,
