rviz error - Segmentation fault

edit

I have installed ROS electric (Ubuntu 10.04).

I get this error message when I like to start rviz with rosrun rviz rviz:

**Segmentation fault**

I tried export OGRE_RTT_MODE=Copy (also PBuffer, or FBO), but it does not work.

Does anybody know an other solution for this problem?

Thanks for help!
