** Description changed:

  In Karmic, DNS lookups take a very long time with some routers, because
  glibc's DNS resolver tries to do IPv6 (AAAA) lookups even if there are
  no (non-loopback) IPv6 interfaces configured. Routers which do not
  repond to this cause the lookup to take 20 seconds (until the IPv6 query
  times out).
  
  *** PLEASE DO NOT COMMENT ON THIS BUG unless you have something
  constructive to say. Everything that can be said has already been said,
  and if you comment, you are just adding noise. Please let those that
  actually know what they are doing concentrate on fixing this bug from
  now on. ***
+ 
+ If disabling IPv6 or using good DNS servers like openDNS does fixes the
+ problem, you are not dealing with this bug. Please refrain from
+ complaining here in that case
