Worked: Possibly never but I'm not sure.
Short description of error
Today I had a once in a lifetime opportunity to make use of the gradient tool in a weight painting case. And then it failed! It seems that when using the gradient tool in weight paint mode, the weights don't get normalized during the stroke.
Exact steps for others to reproduce the error
Click and drag on the sphere. Notice that the influence of Bone2 wasn't subtracted from Bone1.
This tool is extremely rarely used so this is a small issue.
