Comment 7 for bug 586051

Hi Patrick,
I have pushed fix for this in a branch
http://bazaar.launchpad.net/~prafulla-tekawade/drizzle/drz-bugfix-586051

I am expecting some result mismtaches for some of the tests due to (3) above
Could you please run your regular tests and update those results and if you find
everything ok, propose this one for merge ?
