SSH stops at 'SSH2_MSG_SERVICE_ACCEPT received'

Question

When I attempt to SSH to anything from my iMac (SSH, git, etc.), SSH freezes at debug1: SSH2_MSG_SERVICE_ACCEPT received. This only happens on my account; I created a new account as a test and everything worked fine. I did reinstall SSH, but both accounts use the same executable. I can SSH to my computer from other computers, so I'm assuming that the problem lies with ssh and not with sshd.

SSH version: OpenSSH_5.9p1, OpenSSL 0.9.8r 8 Feb 2011
OS X Version: Version 10.6.8 build 10K549
Log: http://pastebin.com/wrugsYhf (I use a custom port, 7742)

Is there anything I can do? Thanks in advance.

Answer 1

Running unset SSH_AUTH_SOCK in Terminal worked for me, though I'm currently unsure why. One thing I did not mention in the body of my question was that I had to modify /System/Library/LaunchAgents/org.openbsd.ssh-agent.plist in order to get sshd to work: here's a link to my org.openbsd.ssh-agent.plist in case anyone in the future thinks they know what caused the problem.
