[Pkg-utopia-maintainers] Bug#559547: __init__.pys present on my system

[Joseph Spiros]

Oh, I should probably note that despite the UserWarning that appears
regardless of my "fix", the last log entry resulted in a working UPnP
server that I was able to access with my Playstation 3.

(P.S. - If you are wondering about the inconsistency, I tend to edit my
prompt to a single "$" when I provide logs like this, but forgot to do
so with the second part of the log.)
