I have searched the internet for a solution of that before subscribed problem.
In my case
sudo chmod +r `locate .ttf|grep -i ttf$
solved the problem. Thanx to you all (to unix cracks... is there a better
solution)
It was the rights of maybe some ttf-files. But I can't tell which one it
was,
I fogort to tell, that to set the rights solves another problem. Maybe one of
you find the right bug report
and can change the next ubuntu update. Please mark this update urgent, because
its an error I think.
The problem was (sorry I have a german version and I try to guess the english
names)
