XSANE no longer works with my CanoScan N1220U since upgrading from Gutsy to Hardy. When I launch XSANE a window briefly reports "scanning for devices", then disappears. I've run the following diagnostics:

don@don-desktop:~$ xsane
Segmentation fault


don@don-desktop:~$ groups
don adm dialout cdrom floppy audio dip video plugdev scanner lpadmin admin netdev powerdev sambashare




don@don-desktop:~$ sane-find-scanner
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.

# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.

Seems that the system recognizes the scanner but xsane does not.
I've uninstalled xsane, removed the ~/.sane dir, and reinstalled xsane.

When I launch xsane, these messages appear in syslog:
