"ignored exception" noise on stderr from test_bencode

[Andrew Bennetts]

There's some noise about ignored RuntimeErrors on stderr in this output:

"""

   /home/andrew/code/bzr/bzrlib (1.16dev python2.6.2)

I don't see that here, so it seems to depend on the platform/python version/etc.

(I'm currently on win32 python2.5)
