Note libpng was just updated to 1.4.5, not 1.5.0, partly due to the aforementioned vulnerability shown on the libpng web site.

Since the request to update to 1.4.x had been outstanding for over a year [1], I think we're unlikely to roll this back now. Please file tickets for ports you find that are broken and we will deal with them on a case by case basis.
