xfce4-session not start after login

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the latest image of the development release - Lucid Lynx. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.

I was not able to reproduce this issue using the latest daily images from http://cdimages.ubuntu.com/xubuntu/daily-live/current/

Are you sure that you selected the 'xubuntu' or 'xfce' session, and not the 'xterm' one?

Yes, i'm sure.
Today i try the daily images.

We'd like to figure out what's causing this bug for you, but we haven't heard back from you in a while. Could you please provide the requested information? Thanks!
