All of the tags in my audio-library are actually UTF--8 (as per the Vorbis comment standard), which means that assuming they're in Latin-1 (and trying to convert them) is the wrong thing to do. Also, when I run on my NanoNote, it looks like the system doesn't even have support for Latin-1--so the conversions fail outright, and which is actually completely debilitating for GJay.
I appreciate that some people need this, though, so here's a patch to add a "./configure --disable-latin1" option.
