Description of problem:
oo.o v2.0 doesn't behave as expected when editing a v1.0 document.

Steps to Reproduce:
1. open an oo.o 1.0 presentation with oo.o 2.0
2. create a new slide with an object
3. double click to add the object and create an openoffice.org 2.0 drawing
4. use the flowchart images, connectors to create a diagram
5. label the flowchart shapes with some text
6. save the presentation and close it
7. reopen the presentation

Actual results:
flowchart images appear to be OK, but all of the connectors and text are
jumbled

Expected results:
no chaos

Additional info:
Everything works as expected if you open the v1.0 presentation and
save it as an odp document *before* you add the drawings.

I think this is a problem with embedding a v2.0 drawing in a v1.0 presentation.
When you "double click to add an object" you are only presented with 2.0
options, even though you are editing an v1.0 presentation.
