    Revert "Remove a non-existing file"
    
    This reverts commit 685262fc5ee1303718360962d9afc41099ade69c.
    
    Please don't remove this file from POTFILES.in.
    
    You need to run 'git submodule init && git submodule update' in your
    git checkout. Damned Lies currently lacks support for submodules,
    thus this error.
