Summary: crash during drag-begin
Classification: Platform
Product: gtk+
Version: unspecified
OS: Linux
Status: NEW
Severity: normal

GNOME version: ---
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:
