Check the sonames on your two libpng packages, and maybe an ldconfig -v to
show which versions of libpng are being linked in. You'll also want to ldd
gd-png and see what versions of libpng are being used.
Welcome to the world of fucked up dynamic libraries...

apt-cache rdepends libpng2 libpng3
will show what needs each package. Try and get rid of one version, if
possible. It sounds to me like you've picked up some bad backports along
the line. Blech. Maybe you need a newer version of one of the libpng
packages...
Hmm, good sigmonster. Maybe that should be extended to properly making
backports and shared libraries... <g>
