well, unfortunately that wasn't my question <wink/>

I do:

t = ('hello',)
l = list(t)

which is the standard tuple->list conversion. And yes,
it does work when I run that code in isolation.

The point is that the above, as simple as it looks,
fails with said exception in a very specific context
(I call this code from within a C++ extension module),
so I'm wondering whether I could have messed up the
python runtime somehow or whether there are other
possible explanations for the exception.
