【求助】MODEM不能激活？？

cyq-racoon

我用的是RH13。0，MODEM驱动已经装好，可是在网络管理里面激活MODEM时，系统提示以下错误：
Component: redhat-config-network
Version: 1.2.59
Summary: TB0b15cc2f redhat-control-network:302:hydrate:AttributeError: 'NoneType' object has no attribute 'clear'
Traceback (most recent call last):
File "/usr/bin/redhat-control-network", line 426, in update_dialog
self.hydrate()
File "/usr/bin/redhat-control-network", line 302, in hydrate
clist.clear()
AttributeError: 'NoneType' object has no attribute 'clear'
Local variables in innermost frame:
clist: None
self: <__main__.mainDialog instance at 0x85abd4c>
refresh: None

请教高手这是什么原因，怎么解决？？？
还有在硬件浏览器已经看见MODEM了，我得MODEM是smart link的
