Well it is some kind of font rendering problem. The default device is
the Cairo X11 device, which uses the Pango layout engine for font
rendering. 

If you set the environment variable FC_DEBUG to 1 before launching your
R session, you will get some debugging information. It is very verbose,
but we only need to see this bit:

First font Pattern has 15 elts (size 15)
	family: "Nimbus Sans L"(w)
	style: "Regular"(w)
	slant: 0(i)(w)
	weight: 80(i)(w)
	width: 100(i)(w)
	foundry: "urw"(w)
	file: "/usr/share/fonts/default/Type1/n019003l.pfb"(w)
	index: 0(i)(w)
	outline: FcTrue(w)
	scalable: FcTrue(w)
