I've been having getting that on my site as well. I've got several redirects using mod_rewrite, so I'm thinking it's possible that the rewrite might be causing it. I haven't seen any other spiders doing it, just googlebot.
I do note that none of the // URLs which Googlebot have been fetching have turned up in results and none appear if I do a site search.
