title: Strange locale issue on arch
body: <p>Recently my gnome-terminal stopped working. After starting it using xterm I saw the following:</p>
  
  <pre><code>(process:3975): Gtk-WARNING **: Locale not supported by C library.
      Using the fallback 'C' locale.
  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
  </code></pre>
  
  <p>It appears to be related to my locale which looks like this:</p>
  
  <pre><code>locale: Cannot set LC_CTYPE to default locale: No such file or directory
  locale: Cannot set LC_MESSAGES to default locale: No such file or directory
  locale: Cannot set LC_ALL to default locale: No such file or directory
  LANG=en_GB.utf8
  LC_CTYPE="en_GB.utf8"
  LC_NUMERIC="en_GB.utf8"
  LC_TIME="en_GB.utf8"
  LC_COLLATE="en_GB.utf8"
  LC_MONETARY="en_GB.utf8"
  LC_MESSAGES="en_GB.utf8"
  LC_PAPER="en_GB.utf8"
  LC_NAME="en_GB.utf8"
  LC_ADDRESS="en_GB.utf8"
  LC_TELEPHONE="en_GB.utf8"
  LC_MEASUREMENT="en_GB.utf8"
  LC_IDENTIFICATION="en_GB.utf8"
  LC_ALL=
  </code></pre>
  
  <p>My <code>locale -a</code> looks like this:</p>
  
  <pre><code>locale: Cannot set LC_CTYPE to default locale: No such file or directory
  locale: Cannot set LC_MESSAGES to default locale: No such file or directory
  locale: Cannot set LC_COLLATE to default locale: No such file or directory
  C
  POSIX
  en_US.utf8
  fr_CA.utf8
  pl_PL.utf8
  </code></pre>
  
  <p>I'm really not sure where all the en_GB.utf8 come from in the output of locale.</p>
  
  <p>I tried locale-gen, as suggested in posts regarding similar issues, but that has not fixed the problem. How do I repair this ? Other accounts on this computer don't have this issue, only mine. I do not remember having done anything in particular that would have caused this. </p>
