backtrace from gdb

I'm experiencing this issue in two different boxes:

 - openSUSE 13.1 with jhbuild - using current gtk master
 - Fedora rawhide - up-to-date

Steps to reproduce the problem:

1. Launch gtk3-demo
2. Go to "TreeView" and expand it - Open "Editable Cells" demo
3. Click on "Remove item" until all the elements are gone
4. Perform a "Left-Click" inside the treeview ("Right-Click" doesn't crash the demo)

Expected result:
Nothing

Result:
gtk3-demo crashes with the following message: 

**
Gtk:ERROR:gtkrbtree.c:1044:_gtk_rbtree_find_offset: assertion failed: (tree)
Aborted

I'm attaching a text file with a backtrace of it.

Just cancel the drag gesture and return early, instead of crashing on
code that assumes there's a model/RB tree.
