Gnome2_private,. gstreamer-0.10 And so on) try logging in again.

3 if not, in the most violent way, the user home backup, and then the home inside the file empty, including hidden files, and then put the/etc/skel directory of the hidden files CP to the user home, attention to permissions, if it is root CP, to change the permissions (with Chown- R put the modified home directory owner of all the files into your normal users), the user's own account CP is OK, so you should be able to log into the
