Mike,
Sorry, I wasn't aware of what you were working on.  Definitely keep going on
trunk then.  I was writing my standard response to people using trunk by
default, and then complaining about stability.   I try to reiterate the
suggestion to use released tags whenever possible.

And you were right Radu was able to fix it quickly.
