Description of problem:
Hello. The attached PNG file causes problems when decoding in viewers and editors, but can be decoded by xulrunner based web browsers without problems.

I checked the ldd output and all the mentioned apps are linked against the same shared object ... /lib64/libpng16.so.16

'gimp' and 'inkscape' decode just 1/4 of the image, but throws no error. 'gthumb' shows nothing, but throws no error. 'kolourpaint' says the format is not supported or the image corrupted. 'eog' says "Decompression error in IDAT".

Is the image really corrupted and xulrunner ignores the error? In that case it's curious, that the result decoded by the xulrunner doesn't look corrupted at all. Anyway I'm reporting this to let you check that.

Version-Release number of selected component (if applicable):
libpng-1.6.3-3.fc20

I copied the image object decoded by firefox to the clipboard, then pasted to gimp and saved as a new PNG. Here's the result. It looks ok to me.

Comment 2 Fedora End Of Life 2015-05-29 10:57:17 UTC
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '20'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 20 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 3 Fedora End Of Life 2015-06-29 15:15:45 UTC
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
