Do you mean the already existing one in delete_frame or adding a new
one?

Neither do I.  Note some of the prerequisites:

- Tooltips must be GTK+ native ones - no crash with our tooltips.

- There must be two frames - no crash with just one frame.

- Deleting the frame must be via Alt-F4 - no crash with C-x 5 0.
