indigo: queue_size keyword needed in publishers

[davetcoleman]

I know you guys don't fully support Indigo yet, but there is a small change that now causes warnings in some of your examples. Particularly when I use the Joint Trajectory Playback Example I get the warning:

baxter_interface/src/baxter_interface/limb.py:98: SyntaxWarning: The publisher should be created with an explicit keyword argument 'queue_size'. Please see http://wiki.ros.org/rospy/Overview/Publishers%20and%20Subscribers for more information.
latch=True)

Says:

As of Indigo not passing the keyword argument queue_size will result in a warning being printed to the console.

So it looks like you just need to edit the python code somewhere to pass it explicitly that flag.

Thanks!

K, I fixed it.
