Hello there, I think I am also affected with this bug. Allowing loopback operations using:
*iptables -A INPUT -i lo -j ACCEPT iptables -A OUTPUT -o lo -j ACCEPT* ... does not really help me. The interesting thing is that the problem started to appear just today, and I have never had any problems since the Wheezy release (May, 4th 2013). I don't know if it is related, but before it started to happen I had a problem to boot into Debian: *Fatal server error: Could not create lock file in /tmp/.tX0-lock * I just rebooted again and now I have the slow dolphin problem. -- with best regards, Volodymyr.
