[Twisted-Python] FilePaging not working?

[Samson Yeung]

Hello all,

I am trying to transfer files over a PerspectiveBroker connection with
FilePager and I've run into a problem. The attached cut-down example
works fine with Twisted-2.5.0, but not with Twisted-8.0 or
Twisted-8.1.0. This is with python 2.5.

On version 8 of twisted, a 0-byte file is created and the client never
finished; but with version 2.5, the full file is transferred.

What am I doing wrong; or is this a bug?

Thanks all,

-Samson
