Show wrong Lens ID in Digikam

Version:           2.2.0 (using KDE 4.7.2) 
OS:                Linux

Exiv2 had a bug that displayed wrong LensID that is now fixed upstream in exiv2
but the LensID is still displayed wrong in the same way in Digikam photograph
properties. Displays "251" instead of lens name (see attached image). This even
after rebuilding libkexiv2 and digikam against the patched exiv2 0.22. I think
this might happen to other Tamron lenses too but have no more to test with.

See Exiv2 bug report: http://dev.exiv2.org/issues/791 there is also a test
picture.

Showing right Lens ID with patched exiv2:
$ exiv2 -pt SBP_3069.JPG | grep -i lens
Exif.Nikon3.LensType                         Byte        1  D G 
Exif.Nikon3.Lens                             Rational    4  17-50mm F2.8
Exif.Nikon3.LensFStops                       Undefined   4  7
Exif.NikonLd3.LensIDNumber                   Byte        1  Tamron SP AF

Exif.NikonLd3.LensFStops                     Byte        1  F7.0



Reproducible: Always

Steps to Reproduce:

image in Digikam and check "Lens" under Digikams photograph properties
