Launching of wg_collada_world in gazebo crashes [closed]

edit

Hi all,

When I launch the wg_collada_world of the simulator_gazebo stack, I get the following error info:

gazebo: /tmp/buildd/ros-electric-visualization-common-1.6.2/debian/ros-electric-visualization-common/opt/ros/electric/stacks/visualization_common/ogre/build/ogre_src_v1-7-3/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.

Also I cannot launch the simple_office2 with the same error info.

Appreciation for any help!
