Short description of error
Blender crashes when Shift+Clicking on the X in the material ID field in the material properties of a grease pencil object (doesn't seem to happen on regular meshes).
Also, interestingly enough it only happens when trying to shift+delete the first material, not with the second or others.
Exact steps for others to reproduce the error
- Open attached .blend file
- Shift+Click on the X icon in the material ID field of a grease pencil object.
