[Voyage-linux] Problem creating database on alix

Hi there, the log didn't helped because mpd was crashing on different files
any of the times I've tried. Being very hangry at that time I've tried to
install mpdpup version 0.9.3 with mpd 0.16.8 and bang!! It updated the
database without problem, even very fast (but probably is the new NAS). It
also solved some problems of the latest version with some internet radios,
that sometime caused mpd to crash and restart (but sometimes not restart at
all). Probably something changed in version 0.17.2 of mpd that was the
first version causing me some random problems, never so big maybe because
since first installation I've always retained the database and only updated
it (because the rebuild from scratch was very low then...). This doesn't
mean that the problem is not some of my files, but sure there is some sort
of bug in latest mpd. So I will try to investigate more on this and let you
know if I find something.
See you.
