Description Daiki Ueno 2015-12-22 08:06:37 UTC 
I believe this is not related to bug 759764, but exposed by that bug.  If I choose "Cancel" on the initial prompt and continue using the app, then close the app manually, it crashes:

inspector: Avoid weak ref problem in object-tree

The object-tree associated with a GtkInspectorWindow is automatically
cleared when the window is destroyed, so make sure we don't try to use
the dead object-tree through weak refs.
