No more cover popup

[Laurent]

Between r2613 and r2634 the 'show cover' functionnality has disappeared.

When I double click on the cover :
      Traceback (most recent call last):
        File "/home/laurent/tlc/exaile/xlgui/cover.py", line 436, in _on_button_press
          window = CoverWindow(self.main.window, self.image.pixbuf)
        File "/home/laurent/tlc/exaile/xlgui/cover.py", line 500, in __init__
          self.builder.add_from_file(xdg.get_data_path('ui/coverwindow.glade'))
      TypeError: GtkBuilder.add_from_file() argument 1 must be string, not None

This is not very important, but as discussed on #exaile, might be easy to fix.

Good catch, fixed in r2636.

I confirm this is now working in r2636. Thanks.
