Skanlite crashes when I click "preview" or "scan". It has worked before, like few months ago. My scanner is Canon LiDE 110. Following error message is given: KCrash: Application 'skanlite' crashing... KCrash: Attempting to start /usr/lib64/kde4/libexec/drkonqi from kdeinit KCrash: Connect sock_file=/home/[user]/.kde4/socket-linux-nxyf/kdeinit4__0 QSocketNotifier: Invalid socket 7 and type 'Read', disabling... QSocketNotifier: Invalid socket 11 and type 'Read', disabling... QSocketNotifier: Invalid socket 23 and type 'Read', disabling... QSocketNotifier: Invalid socket 27 and type 'Read', disabling... QSocketNotifier: Invalid socket 28 and type 'Read', disabling... skanlite: Fatal IO error: client killed Unable to start Dr. Konqi Reproducible: Always Using openSUSE 13.2, Kde Plasma 4.14.6, Kernel 4.0.4-4. I don't know if this is related, but Xsane crashes also when trying to scan with error message: "[1] 4852 floating point exception xsane" Also that has worked before.
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 /Kåre
Created attachment 93019 [details] 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.
Created attachment 93075 [details] 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. Terveisiä Mustasaaresta :) /Kåre
(In reply to Kåre Särs from comment #5) > Can you file a bug report at http://www.sane-project.org/bugs.html as you have the hardware ;) Ok, will do. Thanks.
