Broken: version: 2.80 (sub 74), branch: master, commit date: 2019-07-08 12:40, hash: 27adc4aa33
Worked: (optional)

Short description of error
[I am using blenrig, and I have created a vertex group to weight paint hands, applied armature modifier and applied that vertex group on it but as I switch to weight painting blender crashes. I don't know if it is the addon problem or not though]

Exact steps for others to reproduce the error
Heres a screenshot
From here whenever I go to weight painting mode blender crashes

Hi @blackspark-4

Could you provide us with an example file, so it will be easy for developers to reproduce this issue?
