Acually,in XFCE/Thunar, while browsing Network I get the same result as 
using smbtree, i.e. less that really exists.
What can be the cause?
I'm on Debian Wheezy, so samba is quit old, maybe upgrading will fix the 
problem?
Thanks

Certainly try upgrading first - many changes have been made
in that code.
