I found a bug in Bezier tool

[sohail]

Steps to Reproduce bug
1. Select bezier tool;
2. click on 2-3 point. ( dont exit bezier tool)
3. Press N .
4. Press Ctrl+Z.
And it crashes

It does not happen if we move you the node tool via cursor or press enter before N.
I tried moving to other tools but i think it only crashes with node tool.

Sorry for my bad english.
If you are not able to understand it ,just tell me i will make a video.
