I have the same issue in my debian's installation.
As some people already told , I just comment those "weird" lines  in /etc/fstab and now my auto-mount works fine.
Some information that may help: I used a usb stick to install debian with the image 'Debian GNU/Linux wheezy-DI-rc1 "Wheezy" - Official Snapshot amd64 DVD Binary-1 20130214-12:23'.
 Lines added to my fstab:
/dev/sdb1 /media/usb0 auto rw,user,noauto 0 0
/dev/sdb2 /media/usb1 auto rw,user,noauto 0 0
