Hello, Julien
First:
I have installed the current stable release "etch".
The bug report was done at the time where "etch" was testing.
But, the behavior is the same.
Executed the program "scanimage" through gdb with the command: "gdb
scanimage"
After starting, the command "run" was entered.
After about 10sec execution time, the program was terminated with Ctrl+C.
After termination, the backtrace was stored with the command "bt full".
The complete output can found in the attachement.
My current SANE configuration is in the attachement, too.
If you need more information, let me know.
Regards
Bernhard

# For documentation see sane-mustek_pp(5)
# Global options:
# ===============
#
# option no_epp
#
# Disable parallel port mode EPP: works around a known bug in
# the Linux parport code. Enable this option, if the backend
# hangs when trying to access the parallel port in EPP mode:
#
# # SANE_DEBUG_SANEI_PA4S2=128 scanimage -L
# ...
# hangs here -> [sanei_pa4s2] sanei_pa4s2_readbyte: read in EPP mode
#
# Scanner definition template:
# ============================
#
# scanner <name> <port> <type>
# option <optname> <optval>?
# option <optname> <optval>?
# ...
#
# where:
#
# <name> is an arbitrary name for the scanner (eg. Mustek-1200CP)
#
# <port> is the parallel port to which the scanner is connected
# Possible values are 0x378, 0x278, and 0x3bc. For Linux, the
# mapping between ports an numbers is different for kernel
# version 2.2 and 2.4. Port 0x378 corresponds to lp0 on 2.4 kernel.
# If you are using libieee1284, you can as well use parport0, etc..
# If you use the magic value * the port is probed.
#
# <type> is an identification of the scanner type.
# Possible values are:
# - cis600 (for Mustek 600CP & OEM versions),
# - cis1200 (for Mustek 1200CP & OEM versions),
# - cis1200+ (for Mustek 1200CP+ & OEM versions),
# - ccd300 (for Mustek 600 III EPP & OEM versions)
# - ... more types will be added in the future
#
# <optname> is a name of an option, and <optval> an optional value
# for the option.
# Currently available options for *CIS* type scanners are:
# - top_adjust <value>:
# Vertical adjustment of origin, in millimeter.
# Values between -5.0 and +5.0 mm are possible
# (floating point).
# Default: 0.0
# - slow_skip:
# Boolean option. Disables fast skipping to the start
# of the scan region. May be necessary in case fast
# skipping results in inaccuracies.
# Default: fast skipping enabled
# - bw <value>:
# Black/white discrimination value for lineart scans.
# Pixel values below that value are considered black,
# others are considered white. Range: 0-255.
# Default: 127
#
# Currently available options for *CCD* type scanners are:
# - wait_bank <value>
# usecs to wait for a bank change. Positive integer
# values are possible. You shouldn't mess with this
# parameter.
# Default: 700
# - bw <value>
# Black/white discrimination value for lineart scans.
# Pixel values below that value are considered black,
# others are considered white. Range: 0-255.
# Default: 127
# - top <value>
# Scanlines to skip to the top area. Positive integer
# values are possible. 47 and 56 are values I know of.
# Default: 47
#
#
# Example for a LifeTec LT9350 (Mustek 1200CP clone):
#
# scanner LT9350 0x378 cis1200
# option top_adjust 0
# option bw 127
#
# Example for Mustek 6000P
#
# scanner 6000P 0x378 ccd300
# option top 56
#
#
# Uncomment/customize to your needs
#
# scanner Mustek-600CP 0x378 cis600
# scanner Mustek-1200CP 0x378 cis1200
# scanner Mustek-1200CP+ 0x378 cis1200+
# scanner Mustek-600-IIIEP 0x378 ccd300
#
# auto probing:
#
# scanner mustek-cis600 * cis600
# scanner mustek-cis1200 * cis1200
# scanner mustek-cis1200+ * cis1200+
# scanner mustek-ccd300 * ccd300
