Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-09-16 14:41, hash: c9daab7936
Worked: 2.93 and master from a few days ago

Short description of error
Blender instantly crashes / closes when you click on a clip in the VSE that has keyframes on it AND a Timeline or a Dopesheet is visible at the same time.
This one was quite hard to reproduce because I noticed it on a production file that has lots of scenes and linked libraries in it. I could boil it down to a super simple repro scene.

About file: - It's just a VSE layout with a color clip in it. This clip contains two keyframes on the opacity. It doesn't really matter what channels the keyframes are on. As soon as a Dopesheet or Timeline tries to display them Blender crashes. It might be related to the keyframes drawing optimizations from a few days ago (?)

Exact steps for others to reproduce the error

Open the attached blend file:
Select the clip -> everything is fine as expected
Now add a Timeline or Dopesheet to the layout (e.g. by splitting an Editor or by switching the "File Browser" on the top left to "Timeline" or "Dopesheet"
Blender crashes
I could reproduce it on Windows and Linux

Test File:
#91458.blend
