System Information
Operating system: Linux-4.15.0-54-generic-x86_64-with-debian-buster-sid 64 Bits
Graphics card: GeForce GTX 770/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 390.116

Blender Version
Broken: version: 2.80 (sub 74), branch: master, commit date: 2019-07-08 14:18, hash: a4bc6aca0e
Worked: (optional)

Short description of error
Using JACK to sincronize playhead between apps.
When using blender’s playback controlls, the rest of the apps are syncronized.
but when using the playback controls from the other apps, Blender crashes

Exact steps for others to reproduce the error
In preferences i select
. System > Sound > Audio Device > JACK

In the timeline i select
. Playback > Sync mode > AV - Sync

Clicking play in blender all the other apps works fine, but clicking play in any other app makes blender to crash

I uploaded 2 videos showing the steps i followed:

Using blender + QjackCtr + ardour

I just git bisected this, commit a4c907af77 causes jack transport synchronization to be almost completely broken.

The reason is that screen in ED_screen_animation_play is NULL.

Reassigning to @sergey.
