Groups not working properly

[Chade]

Setting up dynamic_reconfigure with groups results in error from rqt_reconfigure:

Here is the error message:

Traceback (most recent call last):

It doesn't matter, if I only specify the groups name or additional the type (collapse, hide) or the state (true, false).

I tested on groovy and hydro with the same result. I'm using the c++ API and Ubuntu x64.

Thanks. That's rqt_reconfigure's issue. Ticket is opened there.
