BSpline is locking keyboard signals

Summary:

Whenever you create or select a BSPline path, you will not be able to control keyboard actions in the app.

Steps to reproduce:

First way

• Open Inkscape
• Select the Bezier Tool
• Set it to BSpline Mode
• Crete some path with two o three points
• Press ENTER
• Now the keyboard is locked

How to escape

• Manually Switch to Selection Tool and select another object, or
• Right-click anywhere on the canvas and you're done.

Second way

• With the Selection Tool, just select that path
• Now the keyboard is locked (yes, by just a click in that object)

What happened?

The app does not respond to keyboard signals until you escape with the help of the mouse/cursor.
