rviz segfaults on load

edit

I'm not sure if this is the right place to submit this. Maybe it should be a bugreport? I had trouble locating the correct bug tracker.

This is an up-to-date gentoo system with this video card: 01:00.0 VGA compatible controller: ATI Technologies Inc RV620 [FirePro 2260]

and this driver: x11-drivers/xf86-video-ati 6.14.0

$ rosrun rviz rviz
