Some error messages in MiniM

[simoncn]

The message about the NCON frame having an invalid size means that the internal structure of the ID3v2 tagging metadata for this file is corrupt. NCON isn't a legal ID3v2 frame and I'm not sure what software would have written this frame into your files. You might be able to fix the problem by running the file through a converter program such as dBpoweramp or XLD.
