gnome-scan crashes on startup
Last modified: 2008-06-03 14:33:02 EDT
Description of problem:
flegita (gnome-scan) core dumps on start up.
Version-Release number of selected component (if applicable):
[james@jumbovaio]$ rpm -qa | grep gnome-scan
Steps to Reproduce:
1. Start flegita
** (flegita:6643): DEBUG: Initializing gnome-scan 0.6 for flegita (flegita)
** (flegita:6643): DEBUG: gsane-module.c:39: SANE version is 1.0.19
03a58d7f-6663-d6f2-0a2f8cd6-0287443d is dumped
flegita starts and runs properly
Better progress is wmade when running flegita as root - the UI opens and is
useable until the first scan is completed, at which point I get a segfault.
It appears that flegita is attempting to log a kernel module that the ordinary
user doesnt have permission to do
I've not seen such crash on x86_64 F-9, as a normal user. Can you please run
flegita under gdb, collect the backtrace and post the result?
(To run flegita under gdb, run gdb on the commandline line; at the gdb prompt,
type 'file /usr/bin/flegita'; then type 'run'. And if you are able to reproduce
the crash while running under gdb, type 'bt' to generate the backtrace.

running flegita from gdb
Results from running flegita under GDB - I've installed the debuginfo rpm for
gnome-scan, but I guess that this will could be more useful if I install more

Same proceedure, this time running as root.
From where did you get /usr/lib/libmfp.so? What scanner in particular are you
trying to use with flegita when it crashed, and have you installed any closed
source scanner driver?
Ah, yes. Should have thought of that. The scanner is a Samsung SCX-4200,
which comes with its own closed source drivers, which seem to be causing the
Using the information on the web (particularly the instructions at http://
ubuntu-utah.ubuntuforums.org/showthread.php?t=245545 and http://
jacobo.tarrio.org/Samsung_SCX-4200_on_Debian ) I have worked around these
problems and got things working OK.
Sorry for the noise, this bug can be closed as far as I'm concerned.

OK. Actually you could have close the bug yourself, since you're the reporter.
I'm closing it now.
