13388	"English .po not compiled into ""django/conf/locale/en/LC_MESSAGES"" directory."	pavl	Jannis Leidel	"The english version of '''.mo''' files are empty into ""'''django/conf/locale/en/LC_MESSAGES'''"" directory. They must be compiled.

I found it by changing the LANGUAGE_CODE to 'fr' in my project settings. 
Then, in the admin, I set the language to 'en'. 
The method '''javascript_catalog''' in  'django/views/i18n.py' loads the catalog for the 'en' language since it's not the default.
