Caused by cfa53e0fbe

Short description of error
Run below code with mesh has shapekey will cause crash as EXCEPTION_ACCESS_VIOLATION.
bpy.data.meshes['Cube'].shape_keys.key_blocks['Key 1'].normals_vertex_get()

Exact steps for others to reproduce the error

open attached .blend
press run script of text editor,

  or run `bpy.data.meshes['Cube'].shape_keys.key_blocks['Key 1'].normals_vertex_get()` in python console

or

launch blender
add cube
add one or more shapekey to cube
run bpy.data.meshes['Cube'].shape_keys.key_blocks[any_key(0,1,... or "Basis", "Key 1" and so on )].normals_vertex_get() in python console

Test File:
crasher.blend
Append
This crash affect to addon of export .vrm file with VRM_Addon_for_Blender. (https://github.com/saturday06/VRM_Addon_for_Blender)
Thanks.
