Hi-

I came across an error in rviz. I'm running the robot in simulation with a
table and coffee cup, and using rviz to look at the narrow_stereo cloud. I
am up-to-date on the cturtle packages, I believe. The CMakelists in
cturtle/stacks/visualization says rosbuild_make_distribution(1.1.2).

About half the time when selecting points by dragging a box, it crashes with
the following message.

rviz:
/opt/ros/cturtle/stacks/visualization_common/ogre/ogre/include/OGRE/OgreAxisAlignedBox.h:252:
void Ogre::AxisAlignedBox::setExtents(const Ogre::Vector3&, const
Ogre::Vector3&): Assertion `(min.x <= max.x && min.y <= max.y && min.z <=
max.z) && "The minimum corner of the box must be less than or equal to
maximum corner"' failed.
/opt/ros/cturtle/ros/bin/rosrun: line 35: 10195 Aborted
$exepath "$@"

At first it seemed it had something to do with where the rviz view frame was
relative to the robot, or whether I selected the points by dragging from
top-left to bottom-right or vice-versa, but now after many many trials it
seems to crash more or less equally well no matter how I am dragging the
box, or where the rviz view frame is located relative to the robot, so I
suppose that info ends up being somewhat useless. (?)

Does this have something to do with points that you start dragging over no
longer existing by the time you let go of the mouse to form the selection
box?
