Broken: 9efe117535c6, master, 2018-05-20
Short description of error
For normal objects switching a material slot link to Object and back to Data will result in the material to reappear in the slot. For Grease Pencil objects the material in the slot will point to 0xcccc.... This causes blender to crash while rendering the viewport.
Exact steps for others to reproduce the error
- File -> New -> 2D Animation
- Switch Link of material slot to Object (Bottom right button in material slot selector.)
- Switch Link of same material slot back to Data
- Blender crashes on viewport render
