 Shell temporally unzip icon from bundles and creates auto_ptr object
 that object assigned to gtk.Image.props.file that loses auto_ptr instance.
 As result sugar-0.84 can't display icon of activity palette in Journal.

 Attached patch looks like dirty hack but it could affectively handle that
 problem and could be applied only to 0.84 branch(since shell from git
 process icons differently in Journal and doesn't fail)
