I applied the fix in
http://websvn.kde.org/branches/extragear/graphics/digikam/libs/dmetadata/dmetadata.cpp?r1=1165407&r2=1172473
to 1.4.0, and it did not work as expected. Instead of automatically matching
the exact lens, it matched a different lens which had a focal length range that
covered the shortest focal length. In the quick test I did, instead of matching
EF-S 17-85mm f/4-5.6 IS USM, it matched EF-S 10-22mm f/3.5-4.5 USM.

If I instead place the append call with Exif.CanonCs.LensType before
Exif.CanonCs.Lens, then it works as expected.

I should probably build from svn, but assuming no other major changes were
made, I think this is not fixed.

I can supply a sample image if that would help test (I assume some other Canon
DSLRs, such as 40D, work with the Exif.CanonCs.Lens tag, and we actually would
prefer both types to work, not one or the other).
