+TargetMilestone: ---
+Summary: Crash in Listview.
+I was running the winforms/listview sample:
+To reproduce:
+mono swf-listview-items.exe
+Then click:
+1. Add Items
+2. Select an icon.
+3. Now click in between two icons (or the union of four, its easier to hit).
+You get a crash:
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object
