My suggested fix may help that case, as references to frame_data structures
won't be done directly.

I'm not sure anything other than closing the flow graph when you close the
capture will help the "after closing" case.

You can select a packet in the flow graph window and have the corresponding
packet in the main window be selected, which means there's *another* code path
where Hilarity Ensues if you try to use the flow graph window after closing the
capture.

Methinks we should just close the flow graph window if you close the main
window for which it's displaying a flow graph; anybody bothered by that is more
than welcome to submit a change that makes it work....
