Broken: 2.80, Manual build from today commit c358da6b21
Worked: 2.80, Manual build from yesterday (c041e10c9a)

Short description of error
Blender crashes when switching to the UV Editing tab or Texture Paint tab in default startup.
Another type of crash stack trace is generated opening the file from this issue #63969, and then switching to the Animation tab as soon as possible.

Exact steps for others to reproduce the error
Just open Blender and switch to UV Editing or Texture Paint.

I did not split the bugs because they are probably related, but tell me if you would like them to be filed separately.

I can unwrap but only without the UV editor open. If the UV editor is open unwraping crashes directly. Same for the UV reset. It's probably related. This is with the latest build through the buildbot: May 8, 22:00 (GMT?).
The version two or three days ago worked fine, meaning I could unwrap while having the UV editor open.

@fclem, in the future, please don't commit big refactorings in the evening when it's too late to fix issues like this before the next nightly build.

I'm using commit f09aead64a and I can confirm that 6e33729462 fixes the UV Editing tab crash and the crash using the blend file from #63969, but switching to Texture Paint tab still crashes:

Seems the same crash, just with source lines number updated.
