I was dragging and dropping bookmarks in the bookmark editor, trying to sort bookmarks into subfolders.  Doing that crashes the bookmark editor very quickly on dropping the bookmark, after only a few drags&drops.  This makes sorting many  bookmarks between tedious and very frustrating, due to the frequency of the crashes.

Just start konqueror, Bookmarks -> Edit Bookmarks, and start dragging bookmarks around.
