> Damn.  Where does it crash?  Can you get a backtrace?

Yes. I got to crash a few times at exactly the same place as before
(the line number is higher now, because of your patch in GtkWindowPeer.c).
However, it crashes after at least several dozen or hundreds of the 
  java.awt.IllegalComponentStateException: component 
javax.swing.JPopupMenu$HeavyWeightPopup not showing
   at java.awt.Component.getLocationOnScreen (Component.java:1190)
exceptions, which might well have evil side effects.

But here is another place it now sometimes crashes - looks like this
is a bug in gdk itself:

gdb /opt/jamvm/bin/jamvm
(gdb) break gdk_x_error
(gdb) handle SIGUSR1 pass nostop noprint
(gdb) run PR23558 4000
... passes about 3000 iterations
