Well it is simple once you know about it. I have two complaints as
a maintainer of a couple of libpng dependant packages.
1. Why hasn't there been any discussion on debian-devel to actually
let maintainers know that there is this major backwards incompatibility issue,
which is going to create all sorts of user problems. The only reports I
have seen sofar are Bug#126808 and Bug#126904. Have a look in debian-kde
'where have my icons gone threads' to guage the amount of confusion this
issue is causing.
2. What measures are in place to prevent such a monster change
as caused by the uncontrolled introduction of libpng3??
This is a big issue, I'm stll suprised there has been zero discussion
about this and the implications for developers of libpng dependant packages.

The incompatibility as I see it from here is that any application
which depends on libpng2, is only good with libpng2 <= 1.0.12-2 and
upon recompiling will be dependant on libpng3.
libqt 2.3.1-18 has been recompiled and now depends on libpng3, but almost every
other package needs to be recompiled as well :-(
I understand that Philippe Troin, libpng maintainer, is currently on
vacation. Perhaps someone more knowledgeable about the libpng issues
could comment as this is only what I have been able to gather from the
outside looking in.
