I just upgraded to 18.10 and have the same problem. For me, the output when opening a single gnome-terminal is the following.
# watch_fast: "/com/canonical/unity-gtk-module/" (establishing: 0, active: 0) # unwatch_fast: "/com/canonical/unity-gtk-module/" (active: 0, establishing: 1) # watch_established: "/com/canonical/unity-gtk-module/" (establishing: 0) # watch_fast: "/org/gnome/terminal/legacy/" (establishing: 0, active: 0) # unwatch_fast: "/org/gnome/terminal/legacy/" (active: 0, establishing: 1) # watch_established: "/org/gnome/terminal/legacy/" (establishing: 0) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-terminal in Ubuntu. https://bugs.launchpad.net/bugs/1802520 Title: gnome-terminal prints gnome settings daemon log messages (?) every time I launch it Status in gnome-terminal package in Ubuntu: Confirmed Bug description: $ gnome-terminal # watch_fast: "/org/gnome/terminal/legacy/" (establishing: 0, active: 0) # unwatch_fast: "/org/gnome/terminal/legacy/" (active: 0, establishing: 1) # watch_established: "/org/gnome/terminal/legacy/" (establishing: 0) $ Those three log messages printed when I run gnome-terminal are new in 18.10.
