### pr2_tuckarm not working in hydro

I'm trying to make the PR2 tuck its arms using this command:

  rosrun pr2_tuckarm tuck_arms.py -r t -l t


It works in Groovy, but not in Hydro. It doesn't give any error messages: the script launches, but nothing happens. I've also tried several other ways (like writing a script and calling the tuck arms action from code), nothing seems to work in Hydro. Is it something with my settings, or is it truly broken? If anyone could just check if it works for them in Hydro, that'd help a lot.
