Closing sane-backends task, I believe this is a hal bug.
However, I have no idea ATM why this happens; the scanner entry in hal does not even get the 'scanner' argument (as it should get due to /usr/share/hal/fdi/preprobe/10osvendor/20-libsane.fdi), so it's even before trying to fiddle with ACLs. Can you please do the hal debugging procedure as described on https://wiki.ubuntu.com/DebuggingHal and attach the log? Maybe that will reveal an error. Thank you!
