gattrib doesn't handle schematics with unnumbered refdeses

[cnieves]

1) Open test.sch (file->open)
2) Open test_bad_parameter.sch (file->open)
(gattrib:7243): GLib-GObject-WARNING **: invalid uninstantiatable type `(null)' in cast to `GtkSheet'

(gattrib:7243): GLib-GObject-WARNING **: invalid uninstantiatable type `(null)' in cast to `GtkSheet'

3) Hit components, pin and net tabs.
4) Open test_rotated.sch
(gattrib:7243): GLib-GObject-WARNING **: invalid uninstantiatable type `(null)' in cast to `GtkSheet'

(gattrib:7243): GLib-GObject-WARNING **: invalid uninstantiatable type `(null)' in cast to `GtkSheet'

5) Hit components, and pin tabs. (I see two components tabs).

6) Click on one cell (without changing anything), then another, another,.. (5 or 6 times).

7) Open test.sch
  Segmentation fault.

Note: The schematic names mean nothing.

Can't reproduce in current version of gattrib, so I assume application changes since filing have worked round or fixed this issue. There is no file->open menu in gattrib these days, and the pins tab was removed. Opening these schematics in gattrib (from the command line) do not issue the Gtk warnings noted in the description.
