 * Hi Evilex/lingomedia
 * I’ve investigated this a few times and the cause has always been an unexpected
   closure of the server connection. The javascript above is not from my plugin.
   It may be from jQuery, but I’ve never tried to track it down.
 * The cause is likely something like an overloaded server with processes being 
   kill off, or a timeout being hit outside of PHP (ie nginx). I’ve only ever been
   able to reproduce this by starting a big import/export and then killing apache.
   Worthwhile checking your server logs if you can.
 * Best wishes
 * Paul
