[gentoo-dev] Some tarballs still ship broken .png images that can't be viewed with libpng16, "Tracker" bug #468386

[Samuli Suominen]

It would take considerably amount of time to start extracting tarballs,
installing ebuilds, and reporting bugs about possible
broken .png files within packages.
The problem is broken IDAT lenght, an error that libpng15 still
gracefully ignored, but libpng16 no longer ignores.

The bug, http://bugs.gentoo.org/468386
List created by Tobias at 2013 May,
https://bugs.gentoo.org/attachment.cgi?id=347306
<mailto:klausman@gentoo.org>

This has been discussed on the ML before, and most important packages
got already fixed, but there are packages still
left. Any help addressing the issue is welcome, and I'm sending this
mail in hopes people will see packages on the lists
that intrest them, and fix them.

Thanks,
Samuli

No idea how that happened. I blame Thunderbird.

Pretty good idea, there is the script in python, and Portage is python,
maybe it can be adopted somehow.

The script is at, https://bugs.gentoo.org/show_bug.cgi?id=466190#c11

If there exists a tool that detects that broken png files, maybe a QA
portage check (like the one used to detect broken .desktop files) could
be added to help to detect and fix the problematic images :/

Probably we will need to open a bug report, do you prefer to report that
one or should I? ;)
