A simple traceback shows that the bug was actually in code trying
to do exactly what you suggest ;-)

R> vignette("introduction")
Error in sprintf(gettext(fmt, domain = domain), ...) : 
	use format %s for character objects
R> traceback()
4: sprintf(gettext(fmt, domain = domain), ...)
3: gettextf("vignette '%d' found more than once,\nusing the one found in '%s'", 
       topic, dirname(pdf[idx]))
2: warning(gettextf("vignette '%d' found more than once,\nusing the one found in '%s'", 
       topic, dirname(pdf[idx])), call. = FALSE, domain = NA)
1: vignette("introduction")



Fixed now in both r-patched and r-devel.
