Comment (by cypherpunks):

 > I wonder why using Google's DNS settings would result in this behaviour?
 Google do not filters DNS replies, and as said:
 > OpenDNS and many other DNS providers heavily filter and manipulate DNS
 replies

 Client that triggers that message tried streams with target address
 filtered by OpenDNS. If stream failed then no circuit used and no broken
 number of sendme cells.
 It's theory that could explain something.
