reading a python file object in c extension crashes python

[travis ray]

Hi,

I have an extension in which a file object is created in python and
passed down to a c extension which attempts to read from it or write
to it.  Writing to the file pointer seems to work okay, but reading
from it results in EBADF and causes python to crash on exit.

I've attached the minimal (I think) c code, python code, build script,
build log, and run log.  Any and all help is greatly appreciated.

Thanks.
