Hey Asheesh -- sorry we missed this the first time.  I just tried to 
apply it but the patch didn't go through because of the dir naming 
conventions you are using on your system. Could you try to get an svn 
co, apply your patch, and then submit an 'svn diff' ?

That's attached.  Also, try using "patch -p1" next time. (-;
