[Sage] Bug parsing <link>?

[Kirby Files]

Folks,
   A number of feeds use relative URIs in the href for a <link> (see, 
e.g., http://www.intertwingly.net/blog/index.atom, where an example 
href is "2007/05/09/JavaFX-Script", which should be treated as 
relative to http://intertwingly.net/blog/).
   While these are valid URIs, Sage seems to interpret them as 
fully-qualified URIs; the resulting links are of the form: 
http://2007/05/09/JavaFX-Script.
   Could we please have this behavior changed, so that any relative 
URI  (or absolute path) is interpreted in relation to the base URI of 
the feed?

Thanks,
