[Rd] crash after using graphics in Rcmdr (PR#13679)

[DevinJ]

This happens to me every time I try a plot command from TextWrangler with the
following applescript

tell application "TextWrangler"
	set the_selection to (selection of front window as string)
	if (the_selection) is "" then
		set the_selection to line (get startLine of selection) of front window as
string
	end if
end tell
tell application "R64"
	cmd the_selection
end tell

I don't know if that sheds any light on the situation. I do like
TextWrangler but can't use it because any time I send a plot command over it
plots fine with Quartz, but when I close the window (manually or with
dev.off()) I get the segfault.
