Thank you for providing detailed steps to reproduce the problem. I think the use case described is not a common one (for one thing gnome-shell is merely a universe component in Lucid, and not something being actively targeted at this time afaik), but that said, the general issue of this failing when changing between the two seems like a legitimate issue.
Would you mind checking if this misbehavior still occurs with Lucid?
