When attempting to start the Terminal application from Unity Dash, the icon appears, flashes for several seconds, and then disappears. When attempting to start
gnome-terminal from xterm, I receive the following output (line breaks added after colons for easier reading):
Error constructing proxy for org.gnome.Terminal:/org/gnome/Terminal/Factory0: Error calling StartServiceByName for org.gnome.Terminal: GDBus.Error:org.freedesktop.DBus.Error.Spawn.ChildExited: Process org.gnome.Terminal exited with status 127
A cursory search of the issue lead to several suggestions concerning issues with the locale settings, but my locale appears fine:
richard@lappy-x64:~$ cat /etc/default/locale LANG=en_US.UTF-8 richard@lappy-x64:~$ echo $LANG en_US.UTF-8 richard@lappy-x64:~$ echo $LANGUAGE en_US
Any ideas for additional troubleshooting?
