1. Create a default chart (where no object has been moved or resized)
2. Save
3. Remove the positions of diagram, legend or titles (main, sub or axis-titles)
or the size of the diagram in the XML file.*
=> When loading the file the positions and sizes do not match the original defaults.

*Notes:
1. It is a bug that default positions and sizes (except the size in the
chart-element) are written to the file
2. The non-existence of positions and sizes is conforming to the OASIS
specification and should result in the corrrect default positions, including
proper auto-arrangement (e.g. the diagram size changes when you change the
legend preset-position from right to bottom).
3. Other programs like Gnumeric or KChart may ommit the positions and size in
the file. This should result in the proper defaults in OOo 2.0. Specifically, we
plan to ommit the default positions and size in OOo 3.0 (or whatever the next
release might be called)

Testing Notes: As there exist currently no files without positions of chart
objects (except those being patched by hand) I wouldn't test this. For this bug,
it would be enough to ensure that loading of files created with OOo 2.0 works
like before (if the fix is done properly, the exact same instructions should be
executed for files created with OOo 2.0). Note again, that saving will not be
changed, only loading (the import).
