Simple GTK error

["simon kendall" <malicious kendall gmail com>]

Hi all,
I've got a slight problem which I've investigated upon as far as I can
understand, without finding any form of solution. The background is
that I'm writing a function for adding the name of a C++ object into a
listbox - using GStrings for it's nifty functions. The
gtk_list_item_new_with_label only accepts gchars, so I want to change
the GString into a gchar, named label, by taking the internal gchar of
the GString struct and copying it into the gchar.

int AddItemToList(int type, GString *sText) {
                GtkWidget *item;
                gchar *label;
                /*label = sText->str;*/
                item = gtk_list_item_new_with_label(label);

But at the commented line, the program shuts down(using Windows and
can as such not get  a real reason).
Anyone know how to fix this, or an alternate way of solving the
general problem(What with passing in a GString to the function)?

Thanks for any form of attention.
