Paul, thank you for your report. I have a bit of trouble duplicating the issue (although I found another one while trying). To me it sounds a bit like you are running into a file propagation issue for the mirror network unrelated to the packaging. Are you sure that the latest version of libcapi20-3 is available on your mirror? Please have a look at "apt-cache policy libcapi20-3". I don't think this is an RC bug.
