--- Comment #18 from Arkadiusz Miskiewicz arekm@maven.pl --- Looks like this isn't strictly liberation problem. I'm able to reproduce in kmail1 with various different fonts (dejavu, google croscore, vera) when I set to use small font (size less than 11-12). If the liberation font size is 12 then there is no problem.
