Don't free the result of gtk_entry_get_text. As it says on this page
<http://developer.gnome.org/doc/API/gtk/gtkentry.html>: "The returned
pointer points to internally allocated storage in the widget and must not be
freed, modified or stored. For this reason, this function is deprecated. Use
gtk_editable_get_chars() instead."

Also, if you are going to free something from gtk, you have to use g_free(),
not free(), although you can "get away" with calling free() if you don't
ever use any interesting debugging modes.
