Interestingly, that does not start a browser, and options(error=dump.frames)
appears to have no effect, either. geterrmessage() does list the error, though.
I'm not sure whether that is or is not the expected handling of errors inside
Either way, I found I can trigger the error using
tools:::httpd("/doc/html/Search", c(pattern = "grid"))
debugging from there shows that the error is on line
vignettes[i,] <- c(pkg, unlist(vignette[,c("File", "Title", "PDF", "R")]))
At this point, "vignette" is:
File Title PDF Depends Keywords
1 displaylist.Rnw Display Lists in grid displaylist.pdf graphics
2 displaylist.Snw Display Lists in grid displaylist.pdf graphics

It appears, the cause of the problem was failure to "make clean" every once in
a while, and this resulted in installing both displaylist.Rnw and
displaylist.Snw (into a single library location).
