A decoder finding a critical chunk that it does not understand should abort, but finding an unknown ancillary chunk is not an error - maybe his file has an ancillary chunk like zTXt and the GRUB png reader is rejecting it as having unknown chunks. I didn't even take a look at the decoder code so I could be dead wrong, but I think it's a possibility worth investigating... --=-boQj/wT2pMFADSCkiXya Content-Type: application/pgp-signature; name=signature.asc Content-Description: Esta parte del mensaje =?ISO-8859-1?Q?est=E1?= firmada digitalmente -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iQIVAwUASIaawKSl+Fbdeo72AQLcgw//bshprQBwL0+UJ1RZ4pGgrb9IDhZsjLvE HsPRtk+UW8pvdppDdDvzI6yUnZpxZGDItIEy0oRm4RQQmwf76dzfjuTi65Q3rIT+ 1tgNtw6mMn+/KgP1bqNkzqMYQhkyC6gae1g+5es/ieJ2HpS0w62Zh98RspoFrWHc bRp8il9vb9ic1ORpTO2o2Ry8an8eb5MFpPMvBEI9HNWQphkURNv1eXIE6GSR8/7Z xulHF70LkSSE3Ji9ccbXCjvJfj+F561y2868UIY1Nr2hvvp6U/OdlDFs668QP2E1 3s3TnV86oqG7Clj6+X70SvCoCiN64F/kIJ4PuMtp2HXYTcGQahMLdLgxSkHEeXNA ncXuCLTeDUxSJWaA9ldaVH4Y0dgnuA/Yr22keq0zo3jTd+7gWu/k6RfMEW7Dxkkw rgJWqgHJbyx3mv8SGqQsrtF+znhtKTmGj3iTmP35z6o+fkfFff9y4uoSIgsi4+M0 BO/+jGBWd0XccssR7z1F/GUGwETp+EgPgKp2TOh9GfT1m2Pqk4nH504ZU9GRvjyv 8MZSL5zGl4+DSXLeh6Xm4gPhSAljWITQA8JCplUVrOsxYpte04Q6PES10yS4IAqR JMpjaXbnYnTLFugQEfdje9M0yyiFfr5eo/KTVZM6Ku1wVgzBC7MYv2CIwGMCljlD 0zdDdEoP/Xs= =Lrwt -----END PGP SIGNATURE----- --=-boQj/wT2pMFADSCkiXya--
