Couldn't login after an 'automatic logout'

[linux_newbie_!!!]

I was doing some matlab program/amaroK on OpenSuSE 10.1 and the system automatically log me out. After that I couldn't login using that account.
I be able to login using Ctrl+Alt+F1, and there is a .xsession-errors in the home directories with the following message

Could someone please help. Thanks.
