=== Original task description ===
- Open an image
- Create a segmentation
- Open Measurement View
- Draw a line in the Axial window
- Click an move the mouse in another 2-d render window {icon arrow-right} Unhandled exception/Crash
Two things are strange here. First, the crash only happens if there's an image and a segmentation. Second, even though being in line mode, the exception is thrown in GeneratePolyLine()/GetControlPoint() of a PlanarCircle.

It's a segmentation issue!
- Open image

- Continue using it in another render window {icon arrow-right} same crash!
