Short description of error
Blender crashes when a file that has linked BG scene that in turn has nested BG scene(s) Three levels of nested BG scenes seems to cause trouble.
Exact steps for others to reproduce the error
1: make a blend (mine has some text at each step as reference), save.
2: link step 1's blend scene into a new blend and set as the BG scene, save.
3: link the blend from step 2's scene into a 3rd blend and set as the BG scene, save.
4: link the blend from step 3's scene into a 4rd blend and set as the BG scene, save.
5: try to load the saved blend from step 4.
Based on an issue we are having with our production files I tried to replicate an crash. I can't say I can reproduce it without fail but I have a series of nest BG scene blends that crash Blender. Up to the 3rd scene seems OK, but the 4th crashes. If I change the names and text the 4th seems OK, but won't save a new text object in the scene.
