Crash: Moving Isolated Vertices

In some cases, NVil crashes when moving isolated vertices. Try this: Select nothing and enter vertex mode. Activate the 'Vertex Shortcut Tool -> Create/Insert' tool and start creating a polygon. Now either cancel the operation or complete the polygon and undo. You should now have an object which only contains vertices. BTW: The object list doesn't take isolated vertices into account when displaying the number of vertices! Select one or several vertices and try to move them. NVil will crash.
I can sometimes reproduce the bug, when deleting edges from a cube without deleting isolated vertices, but the method from scratch is more reliable in reproducing the crash.

Code: [Select]

System.IndexOutOfRangeException was not handled.
