Thanks for the bug report. I have reproduced the error and fixed it for the next release.

The issue is that the docking pages are not being removed from the workspace at the start of the load and they should have been. So the docking page ends up being disposed (because it was not correctly removed) and then when it is added back as part of the load it complains it is already disposed.

Thanks.

I was so much occupied with this bug I forgot to write any comment beside bare bug report in my post.
