Bug 348696

Thanks for the report!

I guess that you have updated the sane backend during that time?

Try running Skanlite with debug output:

SANE_DEBUG_GENESYS=16 skanlite

You can experiment a bit with the debug level to get different amount of output.
Then attach the output here.

The most probable reason is a bug in the backend as you get the same error with xsane, but the debug output helps to find the problem and can be then directed to the sane project

Output of command: SANE_DEBUG_GENESYS=8 skanlite

There's the output for debug level 8.

Thanks,

Try increasing the debug level a bit because I did not find anything that looked suspicious.

It seems also that you have a problem with KCrash ("Unable to start Dr. Konqi"). With KCrash we would get a backtrace....

You could also install the debug packages for libsane, skanlite and libksane and start skanlite with gdb.

Output of command: SANE_DEBUG_GENESYS=16 skanlite

There's outputs. Installed debuginfos for skanlite, libksane and sane-backends. Couldn't find one for libsane in openSUSE's repository. I run these commands in openSUSE Tumbleweed, skanlite-1.1-3.2.x86_64, Kde Plasma 5.3.1, Kernel 4.0.4-3-desktop.

Thanks!

sane-backends = libsane on Kubuntu, so you installed the correct packages :)

That indeed confirms my suspicion that it is the backend.

Can you file a bug report at http://www.sane-project.org/bugs.html as you have the hardware ;)

What to mention:
1) Canon LiDE 110
2) openSUSE 13.2 RPMs
3) Log
[genesys] SANE Genesys backend version 1.0 build 2411 from sane-backends 1.0.24
[genesys] SANE Genesys backend built with libusb-1.0
4) Crash dump:
Program received signal SIGFPE, Arithmetic exception. [Switching to Thread 0x7fffde643700 (LWP 14930)] 0x00007fffe42be9d7 in gl124_led_calibration (dev=0x7fffd8003e60) at genesys_gl124.c:3143 3143 genesys_gl124.c: Tiedostoa tai hakemistoa ei ole. #Means file or directory not found. 
5) Link to this bug

It would be helpful to try the latest sane version of sabe-backends. On (K)ubuntu there is a special repository (PPA) with the latest sabe-backends (weekly or close to it). Maybe there is something similar for openSUSE... The fall-back would be to try to compile it your self.
