Description Matthias Clasen 2015-11-18 00:06:10 UTC 
open the clipboard example in gtk3-demo, click on the image button, and then *quickly* drag out of the window. If you are fast enough, drag-begin gets emitted when there is already no application window under the pointer anymore, and you get this crash:
