Show the backtrace! Otherwise, nobody is going to be able to help you.

Sorry for that, I'm not enough backtrace friendly. :-\

# execute commands on all servers
session.exec( "hostname" )


# run the aggregated event loop

I think you're right and this kind of exception is not handled by the lib.
I've to reread the lib, but its doc is confusing.
