 The usual idiom is:

    for(iter = iterList.begin(); iter != end; ++iter)
    {
        // do something interesting
    }

 with your code you are entering the loop without checking if you are
 already at the end of it (e.g., if a box has no children).  The fact
 that you are segfaulting inside get_widget() may indicate that your
 underlying pointer is not valid.

 HTH,
