My intention was not necessarily to get a fix here, but rather a first 
statement *if* the bug(?) is in pdfTeX or in libpng. Maybe I contacted 
the wrong mailing list, and should have better talked to the pdfTeX 
mailing list.

I'll happily hand over the issue to the libpng maintainers, however I 
could need some help, what needs to be changed. Is Adams description in 
[1] correct?
