CocoMUD client

At least in the French game this error occurs. Check validity:

Traceback (most recent call last):
  File "D:\src\cocomud\src\ui\dialogs\channel.py", line 92, in OnAdd
    dialog = wx.TextEntryDialog(self, t("ui.message.channels.name"), t("ui.message.channels.title"))
  File "C:\Users\Vincent Le Goff\.virtualenvs\cocomud-jujd1AS7\lib\site-packages\ytranslate\tools.py", line 98, in t
    return FSLoader.current_catalog.retrieve(address, count, **kwargs)
  File "C:\Users\Vincent Le Goff\.virtualenvs\cocomud-jujd1AS7\lib\site-packages\ytranslate\catalog.py", line 241, in retrieve
    "catalog".format(repr(address)))
ValueError: address 'ui.message.channels.title' cannot be found in this catalog

This happens when we try to create a new channel through the Channels... menu.
