That warning is non fatal ... (and can't be removed easily).

You should provide which version (git hash) of texturepacker you compiled and on which platform. Also you should try to provide a stacktrace of the crash (by running texturepacker in a debugger for example).

I have the same error with a PNG file from aeon.nox.5 skin https://github.com/BigNoid/Aeon-Nox/raw/...shadow.png

I use Kodi git version 576ac98869c5e6490a38b55ef48fe8cb0ca4ae84 on Ubuntu 14.04.1 LTS x86_64.

The segfault is in squish::CopyRGBA(), and is caused by grayscale PNG files, libsquish only takes data in 32bit ARGB format, however TexturePacker's PNGDecoder::LoadFile() does not convert grayscale data correctly.

I have patched the PNGDecoder and this works for both sample files posted here:

Code:

Should i create a trac ticket for this?

preferably you create a git pull request if possible
