I can't reproduce, all work fine here.
That error come from anything.el itself (in `anything-get-current-source').
It is not related with anything-python.el specialy.
I suspect you will have the same error with others anything modules
also.

You have to make anything working.
Can you describe how did you install anything, what anything files you
load etc...

Be sure also to use anything-config.el.(it will require anything)
Also, don't add anything-python source to anything-sources, use it only
with function `anything-ipython-complete.'

BTW what is os.fcn? i have no completion on that, but yes on os.fc
Anyway if you forget to launch ipython or to load modules,
anything-ipython complete nothing, do nothing, 
it don't crash if you forget that, it just wait.

So good you have python-mode.el.
