Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
I'm doing a MagLev mod for Space Engineers, and all the rail pieces are just linked to the same 1x1 rail piece with array and curve modifiers.
I'd accidentally kept a curve piece linked to the original, so I tried to make a single copy. Doing so reproducibly crashes Blender.
This happens on Windows 7, 64-bit, 2.77, 2.78 and November 1 Nightly. I used an addon for Space Engineers modding, but the issue happens when it's disabled as well.
Steps to reproduce:
Interestingly, the crash does not happen if you delete the collision geometry on layer 2 first.

Hit another crash. I suspect it's the same one. This one happens because I have the materials linked to object instead of data? Same steps to reproduce, click - [x] on the right and it crashes.

Yep, both cases have same cause, fix incoming.
