Using zsh-mime-setup I have no completions for, say, django:

argument-1 options (_arguments _django (eval))
subcommands (_describe _django (eval))
You could do `unalias -s py' to get your manage.py completion back.
alias -s py=python would also work around the problem without creating
any new symptoms---this makes python execute the file directly, instead
of via zsh-mime-handler, and the python completion function is smart
enough to know about looking for completion for scripts. However, it
ought to be able to work without you doing that.
The problem is that the alias gets expanded to
zsh-mime-handler ./manage.py completing here
(I'm guessing---you don't say specifically but this is the obvious thing
the MIME system would do that would confuse completion without screwing
up execution) and there's no special zsh-mime-handler completion
function. There should be one that translates the command line into
what would be executed by the handler and then completes based on that.
I think the following does the basics. I'm sure you'll let me know
politely if it doesn't.
