I just want to draw attention to the bug report in http://projects.scipy.org/scipy/ticket/1187. Basically, scipy.integrate.ode takes a function as input, and the error occurs if that function returns a tuple (instead of, e.g., a list).
If there isn't a simple fix (I can't tell b/c the error occurs within C-code, which I'm not at all proficient in), then I think this should print a more informative error message.

Ah Now I understand, perhaps providing the actual code to the ticket would avoid confusion.
Here you are replacing a mutable object with an immutable object so that may be an issue.
I was thinking the same; for example, if the input function returns an array it also works fine. I'm not sure whether the correct behavior is to simply cast the tuple to a list or to simply raise a more informative error. Unfortunately, I don't understand the C-code well enough to submit a patch. Best, -Tony
