rviz crashes when subscribe on topic /table_arra [closed]

edit

Hi all!

I have some errors in rviz when I try OrkTable plugin subscribe on topic:/table_arra. I use Ubuntu 12.04, Groovy, tabletop.

When I try use this command: rosrun object_recognition_core detection -c rospack find object_recognition_tabletop/conf/detection.table.ros.ork --visualize

I have this error:

rviz: /build/buildd/ogre-1.7.4/OgreMain/src/OgreNode.cpp:413: virtual void Ogre::Node::setPosition(const Ogre::Vector3&): Assertion `!pos.isNaN() && "Invalid vector supplied as parameter"' failed.
Aborted (core dumped)

and some times i have this error:

rviz: /build/buildd/ogre-1.7.4/OgreMain/include/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.
Aborted (core dumped)

What do it mean?
