Yep welcome to the club. It makes Yahoo look VERY foolish and amateurish when a website has the Yahoo Search Box on it (for site search). Your visitor then uses the search function in hopes to find content on your site. When your site is indexed poorly, all the user gets is either nothing (if Yahoo has "banned" the site and has no internal pages indexed) or they get a listing of these screwy urls that contain nonsense query strings, no page title, or description.
For those who don't know what I am talking about, Yahoo has a search box you can place on your site. Visitors can search for content on your site or the web (by selecting the appropriate radio button). Even if the search is limited to "within this site", the data are still pulled from the Yahoo index. Bad data=bad search results.
I have since removed the Yahoo search box from my sites, and replaced it with Google's.
If that is getting indexed, I'd yank the Yahoo search box immediately; we didn't have the same issue, but on several sites there were some nonsense URLs indexed that appropriate 404s were served up for...unfortunately, the sites lost their rankings likely due to a combo dupe filter on the pages that never existed in the first place.
Of the big three, Yahoo has the most indexing issues, but hopefully with the newish Slurp we'll see some incremental improvements.

Talk about ODD!
I found a Yahoo SERP with the URL from an AdWords Ad - Source Code and all. Cant figure out how it happened and now must do some fancy robots.txt and such to keep dup. content issues away (i think - heck if I know what happened)
Most of the time when we find things like this - we just "shrug" and say, "It's Yahoo!"
