That one got approved and I see no other votes, sorry for the
misunderstanding if I was wrong. I thought the discussion were more on
the general principle more than on the bug at hand.

So to summarize my position there:
- there was a bug that made the test suite failing.
- I fixed that.

Now we can discuss if we want to allow bzrlib to import plugins or not,
but I consider that another problem that need to be clearly specified and
tested.

You may argue that this root problem is not addressed by my patch but I
see no reason to block it during the discussion, but then that wasn't
what the bug was about when I reported it.
