[CLAM] Inquiry about chordextractor output file

[David García Garzón]

No, it seems a latent bug. I will take a look at it. The full backtrace would 
be more usefull in this case. It should appear around that message, at least 
in linux, don't you? How long should the mp3 be to get that error?

David.
