What indicates from my point of view that the issue could be in the driver is that comment#0 reads "xsane and skanlite both segfault" - when two different frontnds crash, the root cause is likely not in the frontends but in a lower level - e.g. in the backend (driver). But on the other hand what indicates that it is not in the driver is that comment#0 reads "worked fine in early 13.1 milestones as well as in opensuse 12.3" and we have the sane sane-backends version 1.0.23 where in openSUSE 13.1 there is only one patch for the avision driver that is not used here(genesys is used here). To find out whether or not it is really in the driver: Per Jessen, does it work with the "scanimage" command? If yes, the issue is not in the driver. If not, please attach debugging information to this bug as described in "Trouble-Shooting (Debugging)" at http://en.opensuse.org/SDB:Configuring_Scanners FYI: If the issue is in the driver there is basically nothing what we at openSUSE could do because we do not have such a scanner (and without scanner one cannot reproduce scanner driver issues because one cannot run the driver without a matching scanner) which means we at openSUSE could also only redirect you to report your issue to SANE upstream so that there is a direct communication between you and the upstream authors. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Per Jessen, does it work with the "scanimage" command?
No, scanimage also segfaults.
If yes, the issue is not in the driver. If not, please attach debugging information to this bug as described in "Trouble-Shooting (Debugging)" at http://en.opensuse.org/SDB:Configuring_Scanners
There seems to be four examples, which one would you like me to do? Let me know if you want a backtrace of any of {scanimage|skanlite|xsane}. xsane is what I've reverted to using on 12.3, works fine. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

(that it triggers in 13.1 is probably due to compiler optimizing this differently.) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

But a backtrace of the plain scanimage command could help, provided there is human-readable debug info therein, see in particular the section "Install -debuginfo Packages" at http://en.opensuse.org/openSUSE:Bugreport_application_crashed I found https://bugs.archlinux.org/task/35549 that reads: ----------------------------------------------------------------------------- Run xsane, select a scanner (HP ScanJet 2400c) leave the settings default and then press Scan. The app crashes with "Segmentation Fault". I run it with gdb and found the problems happens in the libsane-genesys.so.1 .. BUT: scanimage -d genesys --format tiff --mode Color --resolution=300 > image.tiff works well! ----------------------------------------------------------------------------- If it is actually the same issue it indicates that the settings for scanning make a difference. Per Jessen, does scanimage -d genesys --format tiff --mode Color --resolution=300 >image.tiff also work for you? Regarding the higher-level debugging output of SANE: According to "man sane-genesys" that reads: ------------------------------------------------------------------------ Example (full and highly verbose output for gl646): export SANE_DEBUG_GENESYS=255 export SANE_DEBUG_GENESYS_LOW=255 export SANE_DEBUG_GENESYS_GL646=255 ------------------------------------------------------------------------ and according to https://bugs.kde.org/show_bug.cgi?id=326700 that reads ------------------------------------------------------------------------ [KCrash Handler #6 gl646_setup_registers (... ------------------------------------------------------------------------ it seems the hp scanjet 2400 uses the specific GL646 code part of the genesys driver.

No, that also segfaults.

Use the matching packages for your particular system. The packages in the "graphics" development project are only for testing, without any guarantee or warranty, and without any support. As an extreme example, this means if your complete computer center crashes because of those packages, it is only your problem. On the other hand this does not mean that those packages are known to be terrible broken but they are not thoroughly tested so that any unexpected issue can happen. Per Jessen, I assume you are a venturous openSUSE user who likes to try out if sane-backends version 1.0.24 from the OBS "graphics" development project actually fixes it for you (I cannot test it because I do not have such a scanner model). In this case please report whether or not it works for you. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
