404 Page Not Found --> assets

[eluser]Beginers[/eluser]
Hi All i wonder why am i getting this error in my Log.php. sometimes it appears sometimes not.

Code:

ERROR - 2012-10-04 10:19:51 --> 404 Page Not Found --> assets
ERROR - 2012-10-04 10:20:22 --> 404 Page Not Found --> assets

even i have this folder name assets in my root file. is this a bug?
what would be the solution to this problem? please help guys. thank you.

You need to exclude 'assets' from being redirected by .htaccess.
