The jpg thumbnail comes out in landscape for me (bad), and the full jpg 
is portrait (good).

The png image just confuses the issue. Ignore it.

Nautilus also displays the thumbnail incorrectly. This suggests to me 
that the thumbnail provided by gfileinfo is wrong (IIRC gfileinfo can 
provide access to embedded jpg thumbnails). This isn't unusual; often 
cameras are lazy and do not save the thumbnail with the correct 
orientation info.

Paolo: the exiv2 thumbnail-loading code checks for incorrect aspect 
ratios, added in this commit:

http://git.gnome.org/browse/gthumb/commit/?id=91f5888cc49ffddc0d05f0f91a591a4388a50e32

See extensions/exiv2_tools/exiv2-utils.cpp:1399

I guess the other thumbnail sources, which are probably being used here, 
need the same check.
