Expected results:
A pygame windows with some text.

Additional info:
Running this by random mix of Python 2.5/2.6 and Pygame 1.8/1.9 give me exactly the same result. Others examples (with fonts, but ASCII only) are OK.
Comment 1 Łukasz Posadowski 2009-11-23 14:57:12 UTC 
So I finnaly go step by step with fonty.py example and got it:

font.set_underline(1)

This is the problem. If I change to:

font.set_underline(0)

all works fine. I belive that are other ways to make underline, but it's official example and should work.

I have confirmation, that on Windows problem doesn't exist. I'm wating for people with other Linux distros however.
Comment 2 Fedora Admin XMLRPC Client 2010-08-12 07:25:56 UTC 
This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.
Comment 3 Jan Kaluža 2010-08-12 12:32:26 UTC 
This is actually bug in SDL_ttf. It can be reproduced by rendering some text with big font size (usually more than 50pt, that depends on used font). Code which renders underline overwrites the memory if height of underline is bigger than 2 pixels.

I'm attaching patch which fixes this bug.
