Details:

Steps to reproduce:
1. Compile and run the attached testcase. I used jamvm 1.3.0 and classpath
with --enable-gtk-cairo with cairo 0.5.0 and gtk+ 2.40 that comes with fedora
core 3. I did not specify -Dgnu.java.awt.peer.gtk.Graphics=Graphics2D

Expected results:
1. A window with all ASCII characters in a textarea shows up.

Actual results:
1. jamvm crashes with
** (:3318): WARNING **: Invalid UTF8 string passed to pango_layout_set_text()
*** glibc detected *** free(): invalid next size (fast): 0x096888a0 ***
Aborted (core dumped)

Testcase:
import javax.swing.*;
import java.awt.*;
public class testcase extends JFrame {
        public static void main(String[] args) {
                (new testcase()).show();
        }
        public testcase() {
                JTextArea a = new JTextArea();
                setContentPane(a);
                for (int i=0; i<256; i++)
                        a.append("" + (char)i);

                this.setSize(new Dimension(600, 400));
        }
}
