Most people don't know how to clean ~/.xsession-errors either. The best and 
easiest way to clean it is to log out and then log in again. Deleting the file 
is *not* enough, since it stays existing until the last application using it 

The correct way to shrink the file while running is:

	echo > ~/.xsession-errors

But no, I don't know how to clean the journal log. That's a good question.
