title: MongoDB mongorestore failure: locale::facet::_S_create_c_locale name not valid
body: <p>I created a dump with mongodump on computer A (ubuntu 12.04 server). I moved it to computer B (ubuntu 12.04 server) and typed:</p>
  
  <blockquote>
    <p>mongorestore -db db_name --drop db_dump_path</p>
  </blockquote>
  
  <p>It failed and it reported:</p>
  
  <blockquote>
    <p>connected to: 127.0.0.1<br>
    terminate called after throwing an instance of 'std::runtime_error'<br>
    what():  locale::facet::_S_create_c_locale name not valid<br>
    Aborted</p>
  </blockquote>
  
  <p>I've successfully accomplished this operation before and this strange behavior has never occurred. What do I need to do to fix this?</p>
