System Information
Operating system: Windows-7-6.1.7601-SP1 64 Bits
Graphics card: GeForce GTX 770/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 419.35

Blender Version
Broken: version: 2.80 (sub 60), branch: master, commit date: 2019-05-06 16:39, hash: c0432c2385
Worked: version: 2.80 (sub 59), branch: master, commit date: 2019-04-26 06:00, hash: 513b71c89a

Short description of error
When running a function inside a bpy.apps.timers loop (The first function run does not crash),
using keyframe_insert() on an object/bone/etc or running an operator from bpy.ops,
causes Blender to crash.

Exact steps for others to reproduce the error
Click Run Script.

My script runs a modal operator, that performs separate functions in bpy.app.timers, because 2.8's modal does not run indefinitely,
requiring the user to do "SOMETHING" like moving the mouse, whereas I want the operator to run in the background until it's done or cancelled.
At first I found this crash when calling keyframe_insert()
but as part of the unrelated question I wanted to ask below, I found that when calling operators, they now crash instead of just returning an error.
(At least the ones I'm trying to use, which clear the pose or transforms)

unrelated:
Attributes inside bpy.context are not available from timers, meaning context has to be duplicated outside of it.
Is there an alternative? Because I have to opt to creating a global variable like:
Global.context = type('context', (), bpy.context.copy())

Seems like the depsgraph sound commit broke this: 2e582f8ab5 (bisected)
