I think I did hear about this gvfs (as a default setup) thing being new in F9 
and it was causing folks problems when they tried to backup.

I don't know how, but I would try disabling/killing gvfs for a while and see 
if that fixed it.

Red Hat has explicitly indicated they will not be making _desktop_ distros for 
a while, and Fedora seems to be (probably accidentally) making things hard* 
for those folks who need a desktop distro in a networked environment.

*gvfs, gdm configuration ability getting more difficult ( a)need set a 
particular message, b) need to have no users listed on the screen at login, 
except the one that JUST put in the smart card) and a few other items that 
break with NFS/NIS/LDAP in use that I am forgetting right now.
