Brush/plane slice operation causes rare assertion failure

[feneur]

I'm not 100% sure how I got the following error, just using the flatten tool a lot. I'll see if I get it again, but I'll post the error message:

Assertion failed: "idx < si.newv.size()"

Looks like CBrush::Slice is failing to handle certain parameters, but I can't find what values trigger the error. Probably need to check the algorithm carefully to figure out what might be going wrong.

Closing this as duplicate of #1027, since that ticket has more info (crash dumps, etc).
