Initializing multiple environments with different viewers causes crash. #377

This simple script

env = openravepy.Environment()
env.SetViewer('qtcoin') 

env2 = openravepy.Environment() 
env2.SetViewer('qtcoin')

Results in a crash:

WARNING: QApplication was not created in the main() thread.
python: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0.
Segmentation fault

Is it possible to create multiple environments with their own viewers?

@mklingen I noticed the same thing. Rosen mentioned back in 2009 that it was a problem with qtcoin.

In the meantime you can use the package or_rviz and publish the environment to a different ROS topic.
