It seems that the only library that links to png12 in the
gtk-2.0 modules directory is the libpixbufloader-png.so:

ldd /usr/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-png.so
...
libpng12.so.0 =>	 /usr/lib/libpng12.so.0
....

All others in all gtk-2.0 directories are linked to png14.
Oversight when changing the specs ?
