Bug#625509: python3-debian and python 3.3

Hi Colin!

the patch for python3 support in python-debian works very nicely for python 
3.2. I was experimenting with python 3.3 (not in Debian and not even released 
yet!) because I was interested in lzma support and, with the newer python3, 
there looks like there will be test suite failures. 

The last of these is trivially fixable with

    def seekable(self):
        return True

the others look like a change in the way subprocess thinks about communicate() 
but I can't see anything in the 3.3 release notes that discusses this.

I don't know whether this fixing these for 3.2 in wheezy is important or not as 
it's not obvious to me whether these new failures are indicative of unfound 
bugs or changes in python itself.

cheers
Stuart

(PS I know that using a local install of /opt/bin/python3.3 with debian 
packaged modules (chardet, apt and six) in /usr/lib/python3/dist-packages/ is 
potentially asking for trouble, but I don't believe that this is necessarily 
the issue here)
