Using "intelligent scissors"

The relevant entry in my Vim User Manual reads as follows:

| Each time you left-click with the mouse, you create a new control point, | which is connected to the last control point by a curve that tries to | follow edges in the image. To finish, click on the first point (the | cursor changes to indicate when you are in the right spot). |
| SNIP
|
| When you are satisfied, click anywhere inside the | curve to convert it into a selection.

In a trial-run (on a new blank page) everything works perfectly,

However, when I attempt to select a irregular shape from an existing image, something is different. Selecting the control points works; getting back to the first point also works (confirmed by Quick Mask).

Converting the outlined area to a selection fails. Instead of "marching ants" I get an additional (unsolicited) control point,

I am using Gimp 2.2 in a Linux Debian 3.1 environment.

What have I missed?
