Win 7 SP1
I have a simple file with sets of curves parented to empties. The end bevel factors of each curve is controlled via drivers by a custom parameter on their respective top level empties and each hierarchy is grouped . I can't append or link these groups. Blender simply pops out of existence.
Exact steps for others to reproduce the error
Just go into the file and try to append a group from the file attached to a new scene.
