Manage Links segfault when selecting patent then child element
Bug:
Segfault using the Manage Links windows to link two properties.
Step to reproduce:
- Create a cone
- Apply two clip on this cone (one inverted and one not for example)
- Tools > Manage Links ...
- Add ...
- Select Mode: Property Link
- Select Source > Clip 1 (on le left column)
- Click on the ClipFunction
- Then, unfold the already clicked Clip1
- Select Plane
It seems the right pane does not crash with this manipulation though.
