I had the same "title" of bug but no GNOME 3 installed, running Unity after todays (12th) updates. I was using LibreOffice and had several crashes and one big freeze of system so i had to reset it (didn't know what else to do). Then after rebooting theme was half-default and half- old human style, icons were human style too. Another reboot and back to normal and then this bug happend while i was trying to continue writing my CV in LibreOffice :)
Since i haven't got GNOME 3 i reported bug here: https://bugs.launchpad.net/ubuntu/+source/aptdaemon/+bug/759344, hope i didn't do wrong. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/759023 Title: aptd crashed with TypeError: watch_lock() takes exactly 1 argument (2 given) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
