Actually it wasn't the setCursor() call, it was just triggered by the
HideCursorManager in combination with creating thumbnails which were using the
GdkPixbugWriter which had some buggy gdk lock code. Hopefully all this has been
fixed with the following patch:

2006-06-11  Mark Wielaard  <address@hidden>

       * gnu/java/awt/peer/gtk/GdkPixbufDecoder.java (streamImage):
       Takes GdkPixbufWriter.
       (GdkPixbufWriter): Implements Runnable.
       (write(IIOMetadata,IIOImage,ImageWriteParam)): Start Thread for
       data processing.
       (DATADONE): New static final field.
       (data): New field.
       (write(byte[])): New method.
       (run): Likewise.
       * native/jni/gtk-peer/gnu_java_awt_peer_gtk_GdkPixbufDecoder.c
       (Java_gnu_java_awt_peer_gtk_GdkPixbufDecoder_initStaticState):
       Get dataOutputWriteID from writeClass.
       (stream_save_request): Change stream field to writer.
       (save_to_stream): Remove FIXME, call writer.
       (Java_gnu_java_awt_peer_gtk_GdkPixbufDecoder_streamImage):
       Store writer.

If you are still seeing deadlock then please open a new bug report for that.

BTW. It seems there are also some new drawing misfeatures in the latest CVS
code. But these also deserve their own new bug report. Probably caused by the
switch the VolatileImage for the swing backbuffer.
