I run a ububtu 7.04 fiesty fawn system. It was working fine.
Today i was trying out some upgrades on artwork usplashes etc.
once done i wanted to browse to the directories like /bin or /bin or /usr ,etc
but whenever i click the "<" beside the tab showing my user name , Desk top shows for a few seonds & return to the home folder.
I also get a nautilus-debug-log.txt on my home folder whic goes as thus....

This configuration for the debug log can be re-created
by putting the following in ~/nautilus-debug-log.conf
(use ';' to separate domain names):

[debug log]
max lines=1000

Yester day i also enabled root account login in my system by editing a gdm.conf file
'Allowroot=true'

Guys for some more info:
i can view other folders using $ nautilus <foldername>
but when i try to open even my directories inside my user folder the problem repeats.
