Thank you for the report.

With a quick look at the crash-log, it looks like the crash is in the sane-backend (driver). Do you get the same crash with XSane?

Yes the same situation

Yes the same situation

Thanks for the update.

I can see from the logs that it is a Pantum printer/scanner.  It seems that it is not supported by sane (http://www.sane-project.org/sane-mfgs.html), but Pantum has a proprietary sane-backend.

Unfortunately I cannot help much here :( 

I don't know much else than that you would report the issue to Pantum. Maybe they have a scanning application also that does not trigger that bug...
For me the download for Linux was a .deb package made for Ubuntu, maybe the package for Arch, is just a repackaged binary that might not be 100% compatible...? Then it could work on Ubuntu...
