Hi,

I'd like to request a backport of the following changeset:

changeset:   770:3a9d06af8830

date:        Sat Nov 01 20:42:18 2008 +0300
summary:     6541476: PNG imageio plugin incorrectly handles iTXt chunk

It addresses errors caused due to incorrect iTXt chunk handling (e.g.
when it contains non-ascii/UTF8 data).

Thanks,
Deepak
