Random sites visited but not bookmarked show up in location bar autocomplete/search even after all private data is cleared.

Happens with some sites not with others. Once a site gets into the location cache it is there forever, clearing private data does nothing.

Reproducible: Sometimes

Steps to Reproduce:
1. New Linux install, removed firefox 2 and ff2 libs, removed .mozilla config directory and /usr/lib/mozilla***** dirs before ff3 install.
2. Install ff3, No bookmarks besides default install supplied bookmarks.
3. Edit-Preferences-Privacy-Private data set to clear ALL private data on close.
4. Type a few letters of a site in the location bar of a site and nothing shows up. This is expected - no cache yet, new install, never visited the site yet.
5. Browse a few random sites including the site above.
6. Exit browser.
7. Start browser, History is cleared, cookies are cleared, about:cache is clear.
8. Random sites previously visited still show up in the location bar. Type a few letters of a site just visited in step 4 and it will show up in the location bar.

Actual Results:  
Random sites previously visited still show up in the location bar. Type a few letters of a site just visited in step 4 and it will show up in the location bar.

Expected Results:  
Clear private data should clear the location bar cache. The location bar should be getting it's data from bookmarks or history. If history is empty and there is not a bookmark for a given site. Why is that site showing up in the location bar?

Clear private data should work as expected.

Setting browser.urlbar.maxRichResults to 0 or -1 as suggested does not clear the location bar cache. It only inhibits display of the cache.

1. Default setting browser.urlbar.maxRichResults = 12
2. Surf some sites, these sites will then show up in location bar
3. close browser and clear all private history on close of browser
4. restart browser
5. browser.urlbar.maxRichResults = -1 (or 0)
6. location bar pulldown doesnt' work as expected from above maxRichREsults setting.
7. close browser and clear all private history on close of browser
8. set browser.urlbar.maxRichResults = 12
9. close browser and clear all private history on close of browser
10. start browser, location bar will contain sites visited during line #2 above.
