This crash occurs whereby an MPEG-PS file exhibits a .mod extension.
Changing priorities will not fix the problem. As far as I understand, we
would have to remove the .mod extension from the list of known extensions
to "fix" this. libmodplug is too stupid to handle malformatted files. There
is really not much we can do about that. People who care can simply not
build the modplug plugin, or fix upstream.
Aside, I suspect decreasing priority below that of PS, will cause the
"promiscuous" PS demux to claim genuine tracker imputs.
