Bug#808262: www.debian.org: http://planet.debian.org/opml.xml produces an error because there is a non-escaped char " in one feed title

Package: www.debian.org
Severity: normal

Dear Planet Maintainers,

Thanks for working in planet.debian.org and its underlying software.

When I try to see the OPML feed, I got an error:

I think the problem is, as Iceweasel error shows, that the " chars in one feed
title are not escaped.

I'm not sure if this is a bug in the venus software or something particular in
planet.debian.org. I saw that the config file has only the URLs of the
corresponding feeds, so I suppose the title field is retrieved in runtime from
each blog.


Thanks Iain R. Learmonth for noticing this and reporting in #debian-www IRC
channel.
