Login Loop on admin account

Question

I started having problems a couple of weeks ago with logging into my main account, I have 10.6.8, when I login to my main account it will either just be blue or maybe show the background image then will return to the login screen, I could access my guest account fine, so I created a new admin account and used console to grab the log when I tried to log into my original account.  Here is the results, any help would be greatly appreciated.

I suspect a User permissions issue or something launching when you log-in as a possible problem.
