rviz crash: terminate called after throwing an instance of 'Ogre::ItemIdentityException'

[bhy]

After running the simulator a few minutes rviz will crash with the following error message:

Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.

A Google search shows some relevant discussions: http://answers.ros.org/question/192272/possible-limitation-of-points-in-markerline_strip-and-rviz/

According to this discussion, there's a limit on the number of line markers you can show.

We then disabled the RobotPath topic in rviz (which shows the path travelled by the robot), and then it will not crash.

However, if we run the simulator for around 10 minutes and then enable RobotPath, the crash follows immediately.

So we guess the reason is that the path length is exceed some limit in rviz/Ogre and causing the crah.

Thanks for the update. This problem was detected and we are waiting to see the best way to address this limitation of RVIZ. For now we recommend users to leave the robot path unchecked in RVIZ.
