With a system update last week (including ROS) everything worked. But now it isn't working anymore.

There was another update of ROS a few days ago. I couldn't check directly afterwards, but now it isn't working again unfortunately. I have no real idea what's going on. Maybe a jump to an invalid function pointer?

Getting The integrated gazebo version crashes too when I start it without ROS. I built gazebo from original sources this weekend and it doesn't crash. Unfortunately the sourcecode will help. I'll have a look at it this weekend.
