[Rd] make check failure

[gb]

I have built today's R-devel without problem on a fresh installation of
debian testing. However, 'make check' fails. In 
'tests/Examples/tools-Ex.Rout.fail':

> ### * vignetteDepends
>
> flush(stderr()); flush(stdout())

> ### Name: vignetteDepends
> ### Title: Retrieve Dependency Information for a Vignette
> ### Aliases: vignetteDepends
> ### Keywords: utilities

> gridEx <- system.file("doc", "grid.Snw", package = "grid")
> vignetteDepends(gridEx)
Error in if ((!is.null(depMtrx)) && (nrow(depMtrx) > 0)) { :
        missing value where TRUE/FALSE needed
Execution halted
 -----------
Since my debian installation may be incomplete, I checked out R-1.9.1, but
there 'make check' ran without errors.
