Short description of error
When copying texture node from one polygon material to another blender crashes.
Don't mind invisible polygons on the gif. Thats another new bug of new build. This one was there before, On previous build.

Exact steps for others to reproduce the error

1. Have 2 objects. 3 different materials per object (6 materials total).
2. Assign some materials to polygons then some textures to materials on object 1.
3. Then go into edit mode. Select polygon.
4. Copy texture node.
5. Go out of editor mode.
6. Select another object ->edit mode
7. Select polygon
8. Paste texture node and connect it to shader.
9. Repeat steps until crash.
