Can't parse management commands from IPython

[fritz-k]

if (setq python-shell-interpreter "ipython").
Each time I try calling a management command there's just this message that no commands were found:

python-django-mgmt-list-commands: Search failed: "Available subcommands:
"

With python-shell-interpreter unset, c s s opens an ipython prompt as desired, but non-django buffers start a regular python prompt.
I'm running emacs 24.5.1 and IPython 4.0.1.
