I've seen this one.  It seems to work to adjust the first line of
socketValid() to this:

  if ((s != 0) && (thisNetSession != 0) && (s->privateSocketPtr != 0) &&
(s->sessionID == thisNetSession))

This function is in sqXWindow.c.  In the stock version, there is no
check for thisNetSession possibly being 0.

If you are loathe to recompile a VM, it also works to create a file
stating "Socket initializeNetwork", and to start squeak with that file
mentioned on the command line.  But, the above is better.  I'll update
my patches page with it.
