Adsense and robots.tx

My Adsense crawler errors report shows various files supposedly restricted by my robots.txt

They take the form of

http://webcache.googleusercontent.com/s … google.com">http://webcache.googleusercontent.com/search?q=cache:0X2JPl27DlUJ:aplawrence.com/Basics/taskset.html+linux+taskset+%22cpu+affinity%22&cd=5&hl=en&ct=clnk&gl=us&source=www.google.com

with the details varying.

I don't see why my robots.txt would match that (or any of the others):

In Googling around, I found a suggestion to add these lines:

User-agent: Mediapartners-Google

Allow: /

User-agent: Adsbot-Google

Allow: /

User-agent: Googlebot-Image

Allow: /

User-agent: Googlebot-Mobile

Allow: /

I don't know why I'd need to, but I'll try it - are the last two really Adsense related?
