This means a widget was added to a container (a GtkBox apparently)
when it was already inside some other container.

Run the app in gdb with --g-fatal-warnings:
$ gdb ./myapp
(gdb) run --g-fatal-warnings

Then it will stop in gdb at the warning, and you can get a backtrace.

The tutorial is just giving you an example of how to debug GTK
code. ;-)
