Previewer stopped working, other GtkNotebook issues

Created attachment 281394 Gzipped .UI file
Yesterday, trying to update yet another old project, I had a problem with a GtkNotebook, where suddenly its background (i.e. the area right of the tabs, above the actual pages) went transparent (white/grey blocks appeared).
I could not find any way to restore it, so, I reloaded the project - which was already sizable. The contents of that notebook's disappeared (the pages now transparent) and the background, as described above, is also transparent. The contents of the pages is still in the .UI file though!
I tried to view the window in the glade-previewer, but it aborts with:
Gtk:ERROR:gtknotebook.c:1255:gtk_notebook_buildable_add_child: assertion failed: (page != NULL) Aborted
(This was before I added the empty Page 3 for testing)
Attached is the UI as it stands.
Note: A probably non-harmful, but still erroneous message appears when starting the program:
(glade:26770): Gtk-WARNING **: gtk_file_chooser_button_set_property: Choosers of type
GtkFileChooserButton do not support selecting multiple files.
Appears 4 times, even though I have only two GtkFileChooserButton's in the program.
