I am using the mate desktop with startx. When I log out from the mate session, gnome-keyring-daemon generates a segmentation fault and creates a core file: $ lldb -c gnome-keyring-daemo.core -- $(which gnome-keyring-daemon) (lldb) target create "/usr/local/bin/gnome-keyring-daemon" --core "gnome-keyring-daemo.core" Core file '/home/hyogi/gnome-keyring-daemo.core' (x86_64) was loaded.
