My app has a collection of objects which can be viewed either

of giving it its own window.
This works fine with gtk 2.24.28, but I'm getting a segfault with
the same code on gtk 3.16.4. [...]
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?
