Re: gvfsd-smb-browse caused high cpu use

[Hacksign <evilsign gmail com>]

This is something similar to my situation.
But my case is a little bit different.
The address gvfs-smb is trying to access is a LAN address ...
I found it is something related to my /etc/samba/smb.conf
The problem is workgroup in /etc/samba/smb.conf ~
I've changed workgroup value and forgot change it back, after comment 
out this configuration the high cpu load situation disappeared.
Thanks for your help ~ ^o^
