6.2.1 .xsession-errors

[utu]

Upgrading IceWeasel from 3.5.6 to 3.5.10 has reduced most of the flash-video-induced .xsession errors here. I have codified a remaining six types of non-flash-related .xsession errors that I observed. Five of these now represent a minor, but puzzling continuing affliction. I have no reason to believe any of these non-flash-related .xsession-errors represent a performance problem, just an interesting puzzlement.

The second error you are getting - the polkit one is because there are 2 instances of polkit in your autostart. Look in /etx/xdg/autostart and ~/.config/autostart and the last place could be /etc/xdg/lxsession/LXDE/autostart - open the file and check if there is a line for polkit.
You should have only one autostart link for polkit, otherwise this error occurs.
The clearlooks error could be fixed as well. Just look if you have the gtkrc file in /usr/share/themes/Clearlooks/gtk-2.0
Regarding errors 1 and 5 I am still getting them as well. Still no solution for them
