Crash when merging viewpoints of two 3d boxes
Steps to reproduce:
- Open inkscape with fresh canvas
- Create two 3D boxes
- Move a viewpoint while holding shift to uncouple the boxes (side-bug: the other box jumps around)
- Select both boxes with shift-clicks (still with the 3D box tool)
- Drag a box's viewpoint on the other's viewpoint
