Moving TrackPoint broken

in previous versions moving a Trackpoint (for manual correction of trajectories) was possible with "control"+"double click left mouse". Now it gives the following result (without shifting the trackpoint). Build on windows, from master dd31600048af8683d889fdd85649df974ba5251e

the same warning is given for "shift" + "double click left mouse" (I guess it is correct there, I do not know from scratch what the short cut does/did usually)
