Couple of thoughts:

Can you really do that (int) cast on "data"?  Perhaps you need
GINT_TO_POINTER() in the caller and GPOINTER_TO_INT() in
network_read()?

What is the type of WorldList[].output_end_iter?  From the context it
has to be pointer-to-GtkTextIter, and storage for the Iter must have
been allocated somehow.
