Short description of error
I can't be sure, because it's not always occur, but rather often. And it doesn't quite go about Graph Editor Imo pose mode.
Just, when You want to UNDO for example badly positioned bone blender crashes. And this behaviour isn't fresh. It's since I remember, so maybe even from the beginning of 2.70 series. Maybe even earlier.
Exact steps for others to reproduce the error
In pose mode of a more complicated rig, like AutoRig, or just rigify, try to undo bone placement. Can't attach blend, because the file is too large, also it's copyrighted because it's from job.
