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
@@ -57,6 +57,8 @@
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
