Hi, It seems like this crash is a hpaio backend problem. Is it a reproducible problem? If yes, it would be good to run Skanlite with some SANE debugging. With this command line we might get more information. SANE_DEBUG_HPAIO=24 skanlite Then post the output here. (scan as little as possible to avoid too much extra data). Thanks, /Kåre
Hi Kåre, Yes, It's a reproducible problem, it happens every time. I've executed as you said and I got the following from the command line: ------------------------------------------------------------------ Skanlite(12020): couldn't create slave: "Unable to create io-slave: klauncher said: Unknown protocol ''. " Skanlite(12020): couldn't create slave: "Unable to create io-slave: klauncher said: Unknown protocol ''. " Skanlite(12020): couldn't create slave: "Unable to create io-slave: klauncher said: Unknown protocol ''. " KCrash: Application 'skanlite' crashing... KCrash: Attempting to start /usr/lib64/kde4/libexec/drkonqi from kdeinit sock_file=/home/skynet/.kde4/socket-titan/kdeinit4__0 ------------------------------------------------------------------ Have a nice day.
OK, The backend is not HPAIO, it is actualy HP5590, so the proper debug command is probably: SANE_DEBUG_HP5590=24 skanlite Can you run this command? Thanks.
Hi Kåre, I got the following: ---------------------------------------------------------------------- [sanei_debug] Setting debug level of hp5590 to 24.

Thanks for closing the bug! Sorry for not answering earlier. I guess that you have updated also the sane backend. It looks to me like the crash was in the backend... I should have tried that lead... shame on me. Good that it is working now :) /Kåre
Don't worry, that was my fault, I completely forgot the bug was still opened. Yes, the backend is a newer version: [hp5590] SANE backed for HP ScanJet 4500C/4570C/5500C/5550C/5590/7650 1.0.7 [hp5590] (c) Ilia Sotnikov [hp5590] attach_usb_device: Opening USB device [hp5590] attach_usb_device: USB device opened and I'm using skanlite 1.0. Kåre, I see in skanlite a tab labeled as "Scanner Specific Options" with two options: -Extend lamp timeout -Wait for button What are they intended for? If "Wait for button" is for starting the scan when a button in the scanner is pressed it doesn't seem to work. Thanks.
The "Scanner Specific Options" tab contains options that skanlite does not know what they do. They are just provided by the backend. I _guess_ that "Wait for button" is an old feature that was used at some time, but is normally unused today. With the epson2 and epkowa backends the frontend would initiate the scan and the scan would only continue after the correct button was pressed on the scanner. I only have one (Epson) scanner so I can't be sure about what it's supposed to do with a hp scanner ;) Regards, Kåre
