Crash on undo after deleting all nodes in a path

Summary:

After deleting all nodes in a path, Inkscape becomes likely to crash under certain conditions, in particular on undo.

Steps to reproduce:

Original:

• open Inkscape
• draw an ellipse
• change to path
• remove all but top and bottom nodes
• select two nodes and use tool to remove the left side segment (this removes the whole object, reported in another issue)
• undo two times

Minified:

• Open Inkscape.
• Using the pen tool, draw a triangle.
• Using the node tool, select all the nodes.
• Delete.
• Undo twice.
