V-Rep with Groovy
Hello,
I've been having difficulty in using V-Rep with ROS Groovy properly. While the publishers and subscribers work generally with no problems, image related publishers cause the V-Rep simulator crash, e.g. when the scene "rosTopicPublisherAndSubscriber" is run.
I tried to rebuild the ros plugin (libv_repExtRos.so) in the stack that comes with the simulator. What may be the cause?
The log is as follows:

I couldn't diagnose the bug, so I had to downgrade to precise & fuerte, since I have work to do on the simulator.
