Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits

Blender Version
Broken:
37e7e1e77c
Short description of error
Crash/use-after-free when merging some regions.
Exact steps for others to reproduce the error
With the attached file:
ExampleObjectTrack.blend
Added subscriber: @Sergey
Changed status from 'Needs Triage' to: 'Confirmed'
Added subscriber: @Harley
Actually no need to use a 10MB sample file or do any of the stated initial merging.
It crashes in ui_handler_panel() with invalid userdata sent to it.
Merging in the other direction (from Clip Editor) works fine. Also changing the Clip Editor context from "Tracking" to "Mask", everything works. Change view from "Clip" to "Graph" or "Dopesheet", everything works.
