<p>now i was assuming that this "1   Foundation                        0x35ba2210 -[NSPathStore2 stringByAppendingPathComponent:] + 84" suugests that the crash is at line 84 somewhere in the project, so i try to find this, but there is no  stringByAppendingPathComponent: used at line 84 any where in the project, so i am confused that how to find that leak in the project, can any one guide how to find this, thanx and regard.
