This blog doesn't refer to the toolbar but Google tools built into Opera. Interesting nonetheless:

I like Dan's last test:
I put up a brand-spanking-new image, completely unlinked to anything. Downloaded Opera for Linux, fired it up, told it that I was OK with google, and looked at the new URL. Then I shut down Opera.5 minutes 38 seconds later... here comes googlebot!
I have ran several experiments with the IE toolbar when this was first reported - all with negative results. I shall run them again and report back if there has been a change.
If Google isn't doing this now, I'd expect it in the future. With those "Supplemental Results", they already are spidering orphan pages they had found before.

I'm in Adsense and I know from my logs that if I put up a brand new page with Google Ads and look at it via any browser then Googlebot will come running very soon. Every time.
BUT, before you get too excited (like I did)...
This is a special visit with a special tag (Mediapartners-Google). The page visited does NOT seem to make it into the main index until a standard Googlebot crawl arrives, whenever that might be.
Maybe this is what the supplemental index thing is about?
Note that I didn't care which googlebot, nor did I care (other than in a vague academic way) whether the image ended up in google's directory. I just wanted to know whether opera would trigger a visit from google, and it does.
While I've not done any particular testing, the google toolbar doesn't seem to trigger the same sort of fast bot activity. Whether it ultimately triggers any is sonething I didn't look into. It might, or it might not, but I'm not interested enough in the results to go check.
Maybe this is what the supplemental index thing is about?"
valeyard's pretty much said it all, except for the last question (relation between the adsense/mediapartners bot and the supplemental results). The answer to that is pretty clear--there is no shortcut into our index via advertising or adsense. Being an adsense publisher won't help you get any extra pages into Google's search index.
Chndru also put it pretty well.
I then navigated to a brand new site, then checked logs and found a hit from "Mediapartners-Google/2.1"
When you allow opera to Comunicate with google, you do so to allow Google to place text ads (AdWords) at the top of the browser window. Opera generate income from anyone that clicks on these ads through the AdSense program. Mediapartners-Google/2.1 is the AdSense spider used to check a web page and then return relevant ads. You should notice the Ads change each time you visit a new page.
crawler8/9.googlebot.com:Mediapartners-Google/2.1 :http://www.googlebot.com/bot.html
is the name of the bot that has been doing the extra-curricular crawling on my site.
I'm assuming this is the Mediapartners bot.
I have it accessing pages with no incoming links (like mysite.com/controlpanel/admin, and banners/admin) and 'nowhere near' a google adsense instance. Why would it want to crawl the authentication page for my link tracker utility?
The only thing remotely relating those pages to google is the fact that i have used the Google toolbar when visiting those pages.
There's too much of this happening in my logs for it to be a coincidence. There's no other way for these pages to have been known. is there?
curiouser and curiouser.
