Evolution启动出错

今天启动Evolution 2.6时发现启动出错，无法读取配置文件，错误提示为：
Error: An error ocurred while loading or saving configuration information for Nautilus. Some of your configuration settings may not work properly。

点击OK之后，又出现提示：
Adding client to server's list failed, CORBA error: IDL:omg.org/CORBA/COMM_FAILURE:1.0

察看/var/log/messages日志文档，发现纪录：
Sep 24 18:48:33 localhost gconfd (jiad4701-24732): Failed to get lock for daemon, exiting: Failed to lock '/tmp/gconfd-jiad4701/lock/ior': probably another process has the lock, or your operating system has NFS file locking misconfigured (Resource temporarily unavailable)
于是把ior文件改名后再启动evolution就没有问题了。
jiad4701@gepc188:/tmp/gconfd-jiad4701/lock$ mv ior ior.bak
不知道这个问题的症结在哪儿。
