problem: gtk_image gives critical error

[Deependra Shekhawat <openbysource yahoo co in>]

Hello friends,
This is my code:

struct splash
{
        GtkWidget *splash_image;
};
void func1(void)
{
        GtkWidget *img;
        struct splash p;

        img=gtk_image_new();
        p.splash_image=img;     
        
        g_signal_connect(G_OBJECT(button1),
                         "clicked",
                         G_CALLBACK(on_butt_clicked),
                         (gpointer) &p);
}

void on_butt_clicked(GtkButton *button,gpointer data)
{
        struct splash *ptr;
        ptr=(struct splash *)data;

        //some code is here
        
        //following line gives error at execution time.
gtk_image_set_from_pixbuf(GTK_IMAGE((GtkWidget*)ptr->splash_image),buffer);
}

Error is:
(splash_screen:3549): Gtk-CRITICAL **: file
gtkimage.c: line 772 (gtk_image_set_from_pixbuf):
 assertion `GTK_IS_IMAGE (image)' failed

Please help !
Regards
