Bug with loading interlaced PNG image under Linux

[konung]

Subj.
Tested on Lazarus 1.0.2, 1.0.4. Ubuntu 12.04 64bit, and on some other Debian-like.
Under different Win - it's OK.
Project for test in attach.
Any ideas???

PS. Sorry for my awful English.

This is fixed now, it was a problem with ZLib library in 64bit Linux.
