Hum ... it seems that yesterday I smoked some very good stuff. As I
tried many things I got confused myself ... I don't know why the hell
I found a bug there as it was working .... I'm very sorry to have you
spent some time on my problem which even didn't exist (except in my
smoked mind :p)

Thanks you
