In "R version 2.10.0 Patched (2009-11-15 r50445)" on Windows Vista upon issuing help.start() and clicking on Packages I get this.

Packages in C:\Users\Gabor\Documents\R\win-library\2.10

C:\Users\Gabor\Documents/R/win-library/2.10/AER/DESCRIPTION -- Title is missing --
C:\Users\Gabor\Documents/R/win-library/2.10/akima/DESCRIPTION -- Title is missing --
C:\Users\Gabor\Documents/R/win-library/2.10/car/DESCRIPTION -- Title is missing --
C:\Users\Gabor\Documents/R/win-library/2.10/caroline/DESCRIPTION -- Title is missing --
...

Looking at make.packages.html in utils, this code:

    for (lib in lib.loc) {

        pg <- Sys.glob(file.path(lib, "*", "DESCRIPTION"))
        pkgs[[lib]] <- sort(sub(paste(lib, "([^/]*)", "DESCRIPTION$",
            sep = "/"), "\\1", pg))

}

has the problem that lib can contain regular expression characters but is used in the pattern of sub. This could be changed to the following which does not use lib in any pattern. Only the pkgs[[lib]]<- statement is changed relative to the original:

    for (lib in lib.loc) {

        pg <- Sys.glob(file.path(lib, "*", "DESCRIPTION"))
        pkgs[[lib]] <- sort(sub(".*[\\/]", "", sub(".DESCRIPTION$", "", pg)))

}
