[gentoo-user] KDM stucking!

[Jackie]

Starting up Gentoo today and found that after I entered my password in KDM  
and the screen just stuck there with nothing for a while(maybe more than  
1min) and then splash came up.This never appeared before and I don't know  
why.The only thing I did and might have something to do with it is that I  
happened to have deleted the /var/tmp/kdecache-username directory.So,is  
this reason? And what should I do now? Here is my ~/.xsession-errors  
file:http://pastebin.com/7N3A9bCc
Thanks.
