(Keywords: assertion) 

The GTK widget assertion (NS_NOTREACHED) below fails when running the browser/base/content/test/general/browser_tab_dragdrop2.js test because mContainer is unexpectedly *not* null. The purpose of SetParent is to reparent a child window before its parent is destroyed because destroying a parent would destroy the child.
