[sane-devel] xsane and scanimage crashes

[J.S]

My system specs:
	slackware 12.2
	kernel 2.6.27.7-SMP
`	gdb v6.8
	xfce 4.4.3
	sane-1.0.19-i486-3
	xsane-0.996-i486-1
	xscanimage (sane-frontends) 1.0.14
	scanimage (sane-backends) 1.0.19; backend version 1.0.19
	HP Scanjet 5300C

My systems has verified my scanner. From my system command outputs I have this:

#lsusb:
Bus 001 Device 002: ID 03f0:0701 Hewlett-Packard ScanJet 5300c/5370c

#scanimage -L
device `avision:libusb:001:002' is a Hewlett-Packard ScanJet 5300C flatbed scanner

#sane-find-scanner

I'm not sure how to properly bring up debug errors with gdb, but this is what I have so far. To be specific, I tested this on a test machine running the above specs and xsane and scanimage crashes. I also
tested this on my primary machine running the same specs as shown above and it still crashes. I added my user to the scanner group. I was surprised that root wasn't listed. Then I plugged in my usb scanjet to
the computer and powered it on. I started up xsane and it was searching for my scanner device and the program detected it, good. Now in the main scanjet 5300C window, I clicked on "scan" and the program
crashed. I ran gdb and tried to reproduce this crash and I received the following from backtrace.

I ran xsane again and I clicked on "acquire preview" in the preview window and the program crashed. I ran gdb again and tried to reproduce this crash and I received the following from backtrace.

Program received signal SIGTERM, Terminated.

Basically the program crashes when I click on "scan" in the main window and "acquire preview" in the preview window. From the above errors, I'm thinking it's a problem with the driver I'm using which is
"libsane-avision" driver. I checked my scanner with a windows pc and it runs, scans, and saves images with no problems.

I opened up the configuration for avision which was located at /etc/sand.d/ directory, and it contained the exact following info:

# This are the possible options. Normally any scanner
# should work just fine without them - and they are only
# needed for test and debugging. So if you experience problems
# and you solve them with enabling options here, please notify
