[Tomas Popela <tpopela src gnome org>]

commit 53a546d3d8040fa218a9acdafb8915ae231da7ed
Author: Milan Crha <mcrha redhat com>
Date:   Mon Feb 9 14:51:40 2015 +0100

    Prefer g_output_stream_write_all() over g_output_stream_write()
    
    Just to make sure that all data had been written, while the later
    can finish successfully without actually write all the data it was
    requested to write.
