'Strip' from 'outgoing changes' screen messes up the changes list
Created originally on Bitbucket by Anonymous
To reproduce: (1) create and commit some changes (2) Go to 'outgoing changes' screen. (3) right click on the last-committed change, select Modify History/Strip.
Result: Either TortoiseHG crashes, or you'd see the item you just stripped replaced with an arbitrary historical change.
Expected: The stripped item should disappear from the list
