i have a 60 gigs ssd , with 30 gb as /home, i just deleted an 21 gb .xsession-errors file, now i am noting that it grows by few kb each minute

I am not able to make any sense of the file here it is http://paste.ubuntu.com/979279.
Any help would be appreciated
I am on Chakra KDE 4.8.3

There are btw no kwin errors logged in that file.

My recommendation is to disable debugging through kdebugdialog.
