[CentOS] Re: Troubles with NetworkManager

Sun Sep 7 15:57:41 UTC 2008

Now,

When I tried to run the NetworkManager applet manually, i got the same
popup error and with the few more details saying the the activity
icons are missing. This is the default installation; I tried two time
times and nothing is modified in the themes.

Sounds much more like a bug, could someone please confirm it.

[root at localhost ~]# nm-applet
