I have an Hg-flow repo with a feature branch of it which has commits and shows nothing uncommitted (ie. clean working directory). If I then create a new branch (normal branch, not hg-flow) off the hg-flow feature branch, the branch is created OK, but the graph part at the top says "Uncommitted changes", although the detail pane below it shows "Nothing to commit".

Why is it showing Unommitted changes ?
