Summary:  JamVM/Classpath crashes with image loading programs

Original Submission:  I found a strange segfault issue in programs that try to 
load/display images (GIF/JPEG).

Mark and I have located the segfault to occur in
native/jni/gtk-peer/gnu_java_awt_peer_gtk_GdkPixbufDecoder.c Line 226. Here is 
gdk_env used (which probably should be env instead). The real problem seems to 
be, that GTKToolkit is not yet initialized properly.

The following workaround seems to work though:

--- gnu/java/awt/peer/gtk/GdkPixbufDecoder.java 26 Jun 2004 16:06:47 -0000     
1.5
+++ gnu/java/awt/peer/gtk/GdkPixbufDecoder.java 28 Jun 2004 20:34:49 -0000

         System.loadLibrary("gtkpeer");
       }
     initStaticState ();
+    java.awt.Toolkit.getDefaultToolkit();
+    try { Thread.sleep(500); } catch (InterruptedException ignored) { }
   }
   native static void initStaticState ();
   private final int native_state = GtkGenericPeer.getUniqueInteger ();

this means, if we wait long enough for GTKToolkit to initialize, the segfault 
does not occur.

Any ideas how to fix this? Maybe I should add that I tried that with JamVM 1.1.4
