​Hello!

I'm running the ALPS docker container with IPython support (I have the last version of the container): 

docker run -p 8888:8888 dolfim/alps:2.2b4-notebook

I am trying to run the first example from the DMRG tutorial (http://alps.comp-phys.org/mediawiki/index.php/ALPS_2_Tutorials:DMRG-01_DMRG) but I encounter a problem related to the lines of the code which runs, writes and reads the simulation data (script at http://alps.comp-phys.org/static/tutorials2.2.0/dmrg-01-dmrg/spin_one_half.py)​. The script creates input files and task, but nothing more seems to happen and when trying to retrieve the output, there is just an empty list and thus I get an IndexError. Has anyone else encountered this problem? It should be reproducible with the Docker container.

Terminal output provided below. 

Thanks,
