URL to "RSS" (i.e., opensearch) doesn't include the app name

Not sure if this is a bug or a misconfiguration on my side,
but here we go:

I installed the Nutch searcher webapp just by dropping its
WAR file in 
Tomcat's "webapps" directory, so the main URL for
it is (for nutch-0.9.war) 
http://localhost:808
0/nutch-0.9/ . After I perform a search, in the returned

results page all the links that point to internal pages
("help", the various 
"explain" etc.) are correct; however, the link to
RSS is like:

  http://ha
rdware.hk.com/opensearch?query=...

...(which of course doesn't work) rather than:

  http://hardware.hk.com/nutch-0.9/opensearch?query=...

...which instead would work fine.

This also happens in a recent stable build, the #143 if the
version 1.0-dev 
.
