Hi,
I updated my repositories with the scrip in user-scripts yesterday (./update_nrp update all). Since then, I can not launch some experiments,
particularly the iCup Template Experiment. The problem arises from the Models/brain_models/idle_brain.py file,
which sets up the simulation with the parameters min_delay and max_delay.
The relevant part of the stack trace looks as follows:

The easy solution is to remove both these parameters from the idle_brain.py file (which works), but I imagine that somebody put them there on purpose.
Since the last commit on that file is 2016-09-06, and NEST has the latest commit on master 10 days ago, I do not know where this issue comes from.
