sorry about that... I think I ran into a similar problem once or
twice...

would you mind sending as attachment a Hamster with such a bad matrix
attached? just do smth like

Hamster(confusion=confusion).dump('bad_confusion.dat.gz')

and send that resultant file

P.S. no guarantee that it would work as expected -- just my tired mind
typing a line without testing it ;) if it doesn't work -- just send
cut'paste of confusion.sets   so we could recreate it
