I originally experienced a similar problem when I started running Gazebo.
I've done a few things since then, including updating to the SVN version,
recompiling supporting software, etc, so I'm not sure if this will make a
difference, but it's worth a try...

One of the things I had to do to get Gazebo working with my ATI video card
was to make a change indicated in:
http://www.nabble.com/svn-gazebo---shared-geometrie---Segmentation-fault-(core-dumped)-td15409529.html

I'm not too familiar with what is really occurring, but basically I had to
change the preferred RRT mode by updating the .gazeborc file (hidden at
/home/username/.gazeborc for me). The file needs to look something like
this:
<gazeborc>
  <gazeboPath>/usr/local/share/gazebo</gazeboPath>
  <ogrePath>/usr/lib/OGRE</ogrePath>
  <RTTMode>FBO</RTTMode>
</gazeborc>

Originally, RRTMode was set to PBuffer, which was causing me problems. After
changing it to FBO I was up and running.

Hope this helps.
