title: Chrome extension disabled "This extension may have been corrupted" Chrome 63.0.3239.84
body: <p>I have a private Chrome extension that opens a text box and uses input from the textbox to open URLs in new tabs. It was working fine until this past weekend when the Chrome update prompted a new "This extension may have been corrupted" error. On Windows, Chrome will disable the extension, on OSX it will crash Chrome. On both, loading the extension unpacked works fine, only when it is packed into a .crx does it prompt the error.</p>
  
  <p>As far as I can tell, there are no misspelled file paths. What could be the issue?</p>
