locales gone, gnome-terminal doesn't start up anymore

[Danny Milosavljevic]

Hi,

so I've updated to 947a5d47a50252cb0b87b78a8f83f274dec593e2 git guix and now I 
don't have any useful locales.

$ locale -a
C
POSIX

Also, gnome-terminal doesn't start anymore:

$ gnome-terminal
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 8

$ gnome-terminal --disable-factory
Failed to parse arguments: Option "--disable-factory" is no longer supported in 
this version of gnome-terminal.

Sigh... at least xterm still works.
