Short description of error
Undoing in a scene with the following setup causes a crash.
- "link_obj.blend" and "link_obj.2.blend" are linked as groups into "MULTI_link.blend"
- "MULTI_link.blend" is linked as a scene into "CRASHME.blend"
- only if more than one group is linked into "MULTI_link" the crash happens
Exact steps for others to reproduce the error
Select the cube, move it around, undo.
The file should stop display some instances and then crash.
