commit feb3cc4bfc91034451a0a044abd3d885e19c723d
Author: Peter Bloomfield <PeterBloomfield bellsouth net>
Date:   Sat Apr 16 09:48:14 2011 -0400

    Use GDesktopAppInfo instead of GAppInfo
    
    	* configure.in: add gio-unix-2.0 to gnome-extras so we can use
    	GDesktopAppInfo.
    	* src/save-restore.c (config_defclient_save): use GDesktopAppInfo
    	instead of GAppInfo to set Balsa as default client.
