[R] Problem with update.packages on repo with a single package

I've set up a CRAN-style repository to distribute a single package. The
repository contains several versions of the package, I was hoping that
update.packages pointed at this repository would grab the highest
version number. In fact it returns an error:
Error in available[, "Bundle"] : incorrect number of dimensions
This is because the private function .remove_stale_dups in utils, which
is supposed to return a copy of an available.packages matrix with no
duplicates, does not return a matrix in the case where all available
packages are stale except one. To fix this I've made the following
simple change to the utils package in my copy of R, but if I've
overlooked something I'd be happy to hear about it:
Index: packages.R

}
- if(length(stale_dups)) ap[-stale_dups, ] else ap

Thanks,
