This is an Xt error, whereas the first one is an Xlib error. It is easy
to trap it.
You do realize that this will never work? In the current setup all open
X11 devices must be on the same display, and 'display' is ignored if a
device is already open. (I don't know if that is documented: I did not
write the Xlib device nor the help page.)

and R crashes out back to my shell prompt.
If I do X11("foo") as a first command I get a meaningful error and my
R prompt back:
X11("foo")
Error in X11(d$display, d$width, d$height, d$pointsize, d$gamma, d$colortype, :
unable to start device X11cairo
In addition: Warning message:
In X11("foo") : unable to open connection to X11 display 'foo'
So it only seems to be after a *successful* X11() call it that it crashes R.
Can't find anything in latest changes that refer to fixing this.
My system is Ubuntu 7.10 with R 2.7.2 from latest repository, also
happens with an R 2.7.0 binary I've got hanging around compiled from
source and also happens on other systems I've tried.
