This is apparently a known problem with the Samsung drivers, and has been for a while. I've found some additional pages that seem to explain why it occurs, although I think this is still a bug within Ubuntu (in addition to the drivers), as Debian seems to simply fail rather than successfully run xsane as root while a user. I haven't tried to apply this information to a workaround, but if I do I will update.
