This deliberate abort is caused by the gtk-interp.patch from
guile-gtk.  It means that some XEvent has been received for a XWindow
whose corresponding GdkWindow has already been destroyed.  This
shouldn't happen for regular GdkWindows (non-pixmaps), because the
GdkStructure is only freed when the DestroyNotify event has been
received.

That is, as long as the reference counting works right.

For GdkPixmaps, things work differently, and I'm not at all sure if I
have got it right.  Do Pixmaps get XEvents?

However, I just tried testgtk and it seems to work for me.  Maybe it
is a timing problem.  Could you try "testgtk --sync"?

I can't reproduce any of them, sorry.  Does the Guile version of
testgtk, test-gtk.scm, crash on you, too?
