Comment 2 for bug 664631

I've attached a sample file for demonstration purposes that may be able to reproduce the crash (at least on my end, Windows + Inkscape 0.48) .

1 - Open file. Switch to the Node tool and enable transform handles for nodes.
2 - Click on the path, and click/drag to select only the inner nodes (highlighted by rectangle) from the path.
3 - Click on the bottom scale handle and begin dragging somewhere. Down, up, doesn't matter.
4 - While dragging, click the right mouse button to summon context menu. Release both buttons without selecting a command from the menu.
5 - Left-click to dismiss the context menu -- selection now tracks mouse movement with no buttons held. Move the nodes back to their original location and click to complete the drag.
6 - Press Escape to dismiss all selections. There may be visual clutter left behind, a phantom bounding box drawn around two or more nodes of the path.
7 - Select path with Node tool, and select the same nodes again. Notice the bottom transform handle is missing.
8 - Click on a different transform handle and Inkscape crashes with a runtime error.
