The change binds the GtkAbout to the application so GTK+ keeps track of
the about box existing or not, and not us. So it avoids multiple about
boxes being displayed.

Crappy backtrace are the ones run from within the gtk_run_dialog() in
the about dialog callback. When yoy show the about box, and don't
dismiss it, your application is running its main loop from your
gtk_dialog_run() call. If the application crashes, the backtrace will be
from your gtk_dialog_run() call, not from the gtk_main() in main.

It's a simple fix that rids your own code of the book-keeping for this
dialogue.
