[PlayerStage-Gazebo] segfault running gazebo

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hi all,

after attempting to run gazebo0.9/0.10/svn with no luck(segmentation fault,
will try test that again later), i turn to seemed stable version
combinations:

gazebo0.8pre3+ogre1.4.9 under ubuntu8.04

now i can successfully run some of the sample worlds: pioneer2at.world,
pioneer2dx.world, pioneer2dx_gripper, simpleshapers.world, factory.world,
lights.world, map.world, however for others, it got stuck with different
causes. (look like that most are related to OGRE) but quite a few got stuck
with the segmentation fault. I list some of them below for your reference.

btw: i am intending to work with the stereo camera simultaion, so what i am
most concerning about is the sample world : bandit and stereocamera which
got the segfaults. (The error when running bandit.world is more or less the
same as stereocamera.world, but what strange that i remember the first time
i ran it yesteday there is something wrong with  /usr/lib/dri/i915_dri.so,
but it dissappeared this morning. ??)

anyone who has thoughts about the error would be greatly appreciated.
