Sorry to self-reply, but I now see that if I use the special function 
gtk_notebook_detach_tab() to pull the tab out of the notebook, instead 
of gtk_notebook_remove_page() or gtk_container_remove(), then the drag 
to root window works OK on current gtk 3. But that special function is 
new in 3.16, so the question arises: Is there a workaround to 
prevent a crash on gtk 3 < 3.16?
