This could be connected with an oddity that I've seen in desktop Chrome and the android version. They both seem happy to write something to the bookmark when something goes wrong.
One example is that when my previous router couldn't access a webpage after it had lost the adsl connection it would put up a page referring me to my isp. If the original page request had come from a bookmark, that bookmark was hijacked to the 'refer to isp' page permanently. Deleting the bookmark was the only fix that I could find. That was on a win desktop.
I think that it was the same thing on an android pad (time/my memory ratio exceeded), but manifested in a slightly different way. Deleting the bookmark fixed it too.
