Connector between clones is corrupted on load if lowered to bottom

[Dominic Sayers]

A connector drawn between two cloned shapes will have its d attribute set to "M 0,0,0,0" when the file is loaded in Inkscape 0.48.1. This happens if the connector object is lower in the z-order than the objects that it joins.

To reproduce:
1. On a new drawing, draw 2 shapes
2. Add a connector between their centres.
3. Clone each shape and drag to a nearby location
4. Draw a connector between the clones
5. Choose the connector and click on Object | Lower to bottom
6. Save the file
7. Close and re-open the file.
8. On reopening the d attribute is zeroed. The file on disk still has the correct d attribute value.

Note: moving one of the connected clones - after loading a file with connected clones, and initially invisible connectors (due to lowered stack order) - triggers a recalculation of the connectors and correctly updates the connector line.

Not reproduced with Inkscape 0.47,
reproduced with Inkscape 0.48.0 and later versions.
