I didn't have any problems with libmng upgrading from 12.04 LTS to 14.04 LTS. I unfortunately don't know the language the bug report is written in (Spanish, I think), but the key lines from VarLogDistupgradeTermlog.gz are
A se preparar para substituír libmng1 1.0.9-1 (emprégase .../libmng1_1.0.9-1build1_i386.deb) ...

386.deb) ...
dpkg: erro ao procesar /var/cache/apt/archives/libmng1_1.0.9-1build1_i386.deb (--unpack):
arquivo tar do sistema de ficheiros corrompido - arquivo de paquete corrompido
I think that's saying it ran into corruption unpacking the .deb. Probably bad RAM or disk on the submitter's machine.
If there ever was a problem with libmng1_1.0.9, it's probably gone in the current version.
