Bug#743387: libgxps: FTBFS with libpng 1.6

[Nobuhiro Iwamatsu]

Source:  libgxps
Version: 0.2.2-2
User: libpng at packages.debian.org
Usertags: libpng15-transition

Hi!

libpng maintainers have a plan transition of libpng16[0].

libpng16 is already installed in experimental, and we are re-building
the package depending on libpng16.
As a result, we checked that your package was FTBFS.
Would you check also in your environment?
And if you could confirm problem, could you fix this?
