glade-3 crashes inserting widget on page 2 of notebook

[bugssoren]

Simple and repeatable:
With a new Glade project
1. insert a window widget.
2. insert notebook widget into the window
3. select page 2 of notebook
4. attempt to insert a label widget as page 2 child widget

At this point it appears that insert didn't happen. Click a few more times to try to insert the label widget. Basically, Glade has gone unresponsive and is ignoring further clicking. Eventually, crashing out.

Where I first noticed this, was in attempting to cut and paste a grid containing other widgets into page 2 of the notebook. System activity after attempting a paste was consistent with a recursive loop. Causing a memory leak and the machine to becoming swap locked.

Now the work around. Simply place a widget (label) into page 1 before attempting to place any widgets into page 2. Works for the proceedure above as well as the cut and paste.
