Are you trying this with the latest trunk? Second patch from NUTCH-443 should
solve that.

Unfortunately, you can't really fix this. There are a lot of feeds out there
that return text/html or text/plain as its content type. Without some sort of
content-type detection, Nutch tries to make the best detection from file
extension and content-type header.
However, if _all_ your urls are feeds, you can just change ParseSegment and
force it to always parse URLs with feed plugin.

If we are going to do this (provide configuration options for what gets parsed
and what doesn't, default elements, etc.) we should definitely wait a while to
fully understand what use cases people have. So, IMHO, this should be done
later (after this patch is committed and used for a while).

> As discussed by Nutch Newbie, Gal, and Chris on NUTCH-443, the current
> library (feedparser) has the following issues:
> - OutOfMemory when parsing > 100k feeds, since it has to convert the feed to
> jdom first
> - no support for Atom 1.0
> - there has been no development in the last year
> Alternatives are:
> - Rome
> - Informa
> - custom implementation based on Stax
