I followed the steps. On https://wiki.ubuntu.com/Backtrace at Generation/3 the system crashed as well, so I couldn't ctrl-c it and even the ctrl-alt-F1 did not work. But the output file was saved, I attach it.
Reading this file I know what causes the problem by now: my Logitech webcam. This time no scanner was attached to my system. Unplugging the webcam, the program works fine: it says, no device could be found. ** Attachment added: "gdb-flegita.txt" http://launchpadlibrarian.net/21109367/gdb-flegita.txt -- Gnome scan utility crashes the system https://bugs.launchpad.net/bugs/315801 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
