Just an update - the crash actually happens whenever all the edges are
added to ANY MSelectionList, not just the global selection.
Ie, this will crash:
import maya.cmds as cmds
import maya.OpenMaya as om
polyCube = cmds.polyCube()[0]
subd = cmds.polyToSubdiv(polyCube)[0]
selList = om.MSelectionList()
selList.add(subd + '.sme[*][*]')
Also, I figured out why refresh would solve the crash sometimes, and
not other times - depends on whether I'm testing in a full gui or not.
(Sort of a 'Duh!' moment there...)
