This in fact a re-introduction of Issue 8529, but I'll file this as new to make
clear, it is now a 2.0 issue.

Steps:

1. Open Office Draw
2. Draw anything simple like say a square.
3. Attach a dimension line to it. U'll find the Dimension Line in the tool bar, 
under "Lines and Arrow" button.
4. Select all, then do Ctrl-C to copy it.
5. Open a new document in Office Writer and paste it with Ctrl-V (Normal paste, 
not the "Paste Special"). 
6. You should see your drawing (square + its dimension line) properly.
7. save the Office Writer document with the normal file extension for OOo doc.
8. Close the document in Writer. Open it again
9. The square will be at the same place BUT the dimension line moved. It can 
move from a few inches up to 20 pages far away. You may not see the dimension 
line at all if it moved too far away. It can be located be selecting the 
drawing in the document and then by trying to locate the handles.

A workaroud is to use the Paste Special.
