Bug using Bezier_Path

[GoogleCodeExporter]

While I was designing a plant, I have pressed at the button called Bezier_Path. 
Inmediately, a new window appeared but I closed it because I didn't want to use 
this function. After doing that, a new window appeared saying: "No point can be 
loaded". I pressed the "accept" button and the program closed unexpectedly.

This problem was solved by adding a condition that checks if the created shape 
is null or not. If Bezier_path points haven't been created, the shape value was 
null so the program stopped unexpectedly.
