Normally, the only thing that gscan2pdf does between the last line of your output and actually quitting is to kill the threads and any other subprocesses.
It looks to me that the Sane thread is not closing cleanly. Do you turn off your scanner before quitting gscan2pdf? What happens if you switch to the scanimage frontend (in Edit/Preferences)? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1268592 Title: gscan2pdf no longer launches in Ubuntu 12.04 LTS after ppa upgrade earlier today To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gscan2pdf/+bug/1268592/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
