If you only want to force animation refresh, you can simply tag the relevant animdata->recalc with ADT_RECALC_ANIM and it will do that
@aligorith yep, realize that.

May as well do both and once, its not really much effort.
@mont29: I think animators would beg to differ - Being able to do that is pretty much essential to being able to add constraints for grabbing/hanging on to props.
Grmlll… And yet, code explicitly allows adding constraints to locked bones… Have to dig this more.
OK, so in your ref.blend file, all bones of the armature are in a protected layer. This implies you should not be able to edit them (like adding a constraint).
Issue here is adding a constraint to a bone of a proxy armature (any constraint does the same).
There are two intersecting islands in the area highlighted with the grease pencil there: http://www.pasteall.org/pic/show.php?id=84854
You cannot view it because it's probably a centimeter or millimeter STL, while Blender assumes by default a meter unit. Just use 0.01 or so as import scale, and you'll get a reasonably sized model.
It's most likely just a self-intersection happening somewhere across those pile pf vertices.. This situations are handled differently in Inkscape and Blender.
@jallwine please do not report bugs about old Blender versions, official one is currently 2.73a, and we are about to release 2.74…
"Please don't add features before you get the existing features fleshed out." -- what I meant with that, is that you should remove the lighting rig from the code. Don't add things until the base functionality is good.
Hi, it is maybe a driver problem or GT 9400 is to old but I think so.
