The response I got at the time from Brendan Cully:

        "Ah, yes, that's correct. The problem is that your MP3s are
        encoded as VBR (which is incidentally why 0.1 crashes on
        you). 0.2.2 has a possibly ill-considered feature that avoids
        reencoding files if they are already at the same bitrate
        as the target bit rate. But it determines the bit rate by
        reading the first MP3 frame only, so it is easily fooled
        by VBR files. The next release, when I get a couple hours,
        will either revoke this feature, make it optional, and/or
        try to detect VBR files and unconditionally reencode those."
