 @manuq: how we should implement this?

 Nowadays, when an error occurs when a page is loading we load a error page
 in HTML format inside the same WebView that is being used.

 The PDF case is a bit different because we do not create a WebView,
 instead of that we create a DummyBrowser and start the download process
 using a WebKit.Download and when it finishes we use Evince to show the
 PDF.

 At the moment we have the signal 'error' of the WebKit.Download connected
 to log the reason. I think we should do something there to show the error
 page

 I see two possibilities here:

  1. Create a common Browser -or a WebKit.WebView- (not a DummyBrowser) to
 show the error page.
  1. Create a Gtk widget that looks similar to the error page (something
 like the PDFMessageBox that you created.

 Any other idea? What do you think?
