Public bug reported:
Sane finds the scanner, but crashes even as root "glibc detected ***
scanimage: double free or corruption" when attempting to open USB
scanner on multifunction (print/scan/copy/fax) Samsung SCX-4521F.
Using Intrepid AMD64.
Sane 1.0.14-6
Printer works fine after installing package from Samsung, trying to open
scanner with Samsung software also results in crash.
sudo 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.

# Not checking for parallel port scanners.
# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.
