[J.H.M. Dassen (Ray) <jdassen src gnome org>]

commit de4df695e736bf260b2c0f3b50a7f0b0b9c9ee99
Author: J.H.M. Dassen (Ray) <jdassen debian org>
Date:   Thu Sep 9 13:58:27 2010 +0200

    Initialise "so".
    
    "so" not being initialised triggered three paths leading to a "Pass-by-value
    argument in function call is undefined" situation as identified by
    LLVM/clang.
