        * lines, the value will get cut at the end of the first line.
        *
        * If the file data is not within that first 8 KB, then the author should correct
        * their plugin file and move the data headers to the top.

 * means fopen returns false because the file does not exist or does not have read
   permissions.
    in my opinion it is not a bug but an incorrect configuration of
   the web server for theme or plugins.
