"You shut down your computer because of a problem." keeps displaying on every boot

I am using a 13" MacBook Air (late 2013 model) with OS X Mavericks.

Yesterday, my computer hung up and gave me a kernel panic error where it told me in different languages that I needed to restart it. Since that restart, it gives me a notification/warning saying, "You shut down your computer because of a problem." every time I boot it up. I am a Mac Newbie and so dont know what to do. Most articles on the internet deal with what to do when that warning shows up. None of those tell you how to get rid of that warning. My computer is running absolutely fine though.

I also repaired the disk using the OS X Recovery Menu and it said it repaired successfully, but the warning is still there. I don't have a backup for time machine.

Adding the log that I found after logging into the main account:

I use a secondary account for my primary use (friend of mine who is a mac enthusiast suggested me to not to use the admin account for my primary use). So when I logged into the MAIN ADMIN ACCOUNT (that I do not use), I found the notification at the desktop (after the usual warning before the boot), I clicked on REPORT and saw the log (added the log to the main question). After I quit the log and restarted again, voila! No warning now! Back to business as usual.
