Well it doesn't sound like anyone is interested in fixing this.
I made a change in sqUnixX11.c to print something better than "X
error" when there is an error:

static int xError(Display *dpy, XErrorEvent *evt)
{
  char buffer[500];
  XGetErrorText(dpy, evt->error_code, buffer, sizeof(buffer));
  fprintf(stderr, "%s\n", buffer);
  return 0;
}


Now I get:

$ ./squeak 
BadValue (integer parameter out of range for operation)
BadColor (invalid Colormap parameter)
BadWindow (invalid Window parameter)
BadWindow (invalid Window parameter)
BadWindow (invalid Window parameter)
BadWindow (invalid Window parameter)

I don't have a lot of time to look into this now but if someone
doesn't pick it up I'll take a look again later when I have more
time.
