I don't know if it is the same problem, but, from some time, I'm getting
this:

 GWorkspace[3627] X-Windows error - BadWindow (invalid Window parameter)
          on display: :0.0
                type: 0
       serial number: 13453
        request code: 2

with GWorkspace, when I switch from Browser view to Icons view.
It seems that the problem has happened the first time when this change has
be done in back:

* Source/x11/XWindowBuffer.m (-dealloc): Free the shared memory pixmap (if
one was allocated).

* Source/art/composite.m: When checking whether the overlap handling
should be used, compare windows, not gstates.
