package search results gives seemingly unrelated package description

When I search for the Ubuntu package adobe-flashplugin (using the text box at https://launchpad.net/ubuntu), I get this as my search result:

adobe-flashplugin
This project is for requesting, processing, testing, and coordinating packages in the jaunty-backports repository. Information on how to effectively contribute can be found at https://help.ubuntu.com/community/UbuntuBackports Please read the "How To Request Backports" section before requesting a backport
Available in: hardy, lucid, maverick, natty

Actually clicking the link to go to that search result (which was the only search result) brought me to https://launchpad.net/ubuntu/+source/adobe-flashplugin, which has no corresponding summary text because it has no upstream connection.

I wondered why the search result for the adobe-flashplugin package showed this seemingly unrelated (or only peripherally related) summary, so I searched Google for the (quoted) text of the first sentence of that description, and found https://launchpad.net/ubuntu/jaunty/+source/adobe-flashplugin, which (as is to be expected) has Jaunty Jackalope Backports (https://launchpad.net/jaunty-backports / https://launchpad.net/jaunty-backports/trunk) as its upstream connection.

So it seems that when an Ubuntu package has no upstream connection itself but has one in some Ubuntu release, the description from the upstream connection is given in the Launchpad search result for that package. (Or perhaps this is not a valid generalization, and I have simply stumbled upon some weird glitch in Launchpad's search engine.) In this case, and I would think in a number of others, this is very confusing.
