Cannot Mount Volume

[Norm]

Recently I have had a problem mounting my Flash drive
I  am using core 6 fully patched. after the original problem with core 6 
not automatically mounting a flash drive when it booted to level 5  a 
new patch removed that problem now it seems to have returned in a new way.
I can mount the drive using a variety of techniques from command line 
options to log on as root, log out and log on as a user.
It is only when I log on as a user directly from a boot that I have the 
problem (it started last week).  As I am in the process of setting up a 
laptop for my 84 year old father for Christmas I don't want to deal with 
explaining command line or logging on as a root first.
When I open "computer" as  a user and then attempt to open the flash 
drive the error message I get is
"Cannot mount Volume
Error org.freedesktop.Dbus.Error.AccessDenied.

A security policy in place prevents this sender from sending this 
message to this recipient, see message bus configuration file(rejected 
message had interface "org.freedesktop.Hal.Device.Volume" Member "mount" 
error name"(unset)" destination "org.freedesktop.Hal")
 From what I can determine it is not associated with SELinux and even 
after I tried a fresh install using default install settings the same 
problem occurred. Have others had a similar problem recently?
