emacs が"GConf Error:"が出して起動しない場合の対処方法

emacs が以下のエラーで起動しない場合は

GConf Error: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/ for information. (Details - 1: Failed to get connection to session: /usr/bin/dbus-launch terminated abnormally without any error message)

gconf2 をインストールすればよい。debian なら

$ sudo apt-get install gconf2
