System Information
Operating system: Windows 10 64-bit
Graphics card: Geforce GTX 1080

Blender Version
Broken: 2.80 beta, 606223f6a61, blender2.8, 2018-12-07
Worked: 2.79b

Short description of error
When creating a simple script, trying to open or access a generated animation Action causes Blender to crash if you duplicate a bone from Edit Mode in the same script.
Trying to open this new action in the Action Editor immediately crashes Blender.

This small script replicates the crash:

import bpy

bpy.ops.armature.duplicate()
bpy.data.actions.new("Action")

Exact steps for others to reproduce the error
blender_bug.blend

Run the script in Edit Mode.
Then try to browse to the new Action in the Action Editor.

Confirmed.

Maybe @Sergey could check on this one?
