Well, I think I've been through this mud before. Though I have been
out of touch for long, it seems the problem lies in

const TagLib::FileRef f(path.toUtf8().data());

Here path.toUtf8() creates a QByteArray which is (as per my
knowledge/or lack thereof) deleted as soon as it goes out of scope.

So, following my theory, any success with
const TagLib::FileRef f(path.toUtf8().data());
const TagLib::MPEG::File f(path.toLocal8Bit().constData());
is a matter of chance.

You can try by, e.g.:
QByteArray a = path.toUtf8(); OR path.toLocal8Bit()
const TagLib::MPEG::File f(a.constData()); OR a.data();

Please correct me if I'm wrong. (I've not practically tried this)
