Please describe the problem:
Glade-3.1.5 has corrupted a project I've been working on in glade-3.0.x. I'm attaching the XML file. You can see in glade that I have all notebook pages visible, including 'Todays Follow-Ups' and 'All Aged Billing Follow-Ups'. But when my app loads up the glade file, I lose the 'Todays Follow-Ups' page ( invisible ). *Some* of the widgets in this page still exists. For example my treeview still seems to get populated, but when my code tries to set_fraction() on the progress bar ( in the page header tab thing ), it doesn't exist. It certainly used to. I suppose to test you can just call get_widget() or glade_xml_get_widget() or whatever it is ( I'm a Perl developer ) on TodaysFollowUpsBar.

Steps to reproduce:
1. Take complex project with notebook
2. Add a page
3. Save project
4. Run app and examine the notebook


Actual results:
2nd last notebook page is missing. Some widgets still 'exist', though aren't visible. Some widgets don't exist at all.

Expected results:
2nd last page should remain as it was before adding final page ...

Does this happen every time?
Haven't tried it again. Reverting to 3.0.x. Sorry.
