Hi Edgar,

Thanks for sending this.  What you describe is how it SHOULD work, but it
seems like we've had a regression, as I'm seeing the same behavior as you.
 This is a perfect example of why the Quantum team is going to use the Bug
Squashing day next thursday to focus on improving unit + integration tests
so we have better code coverage.  Hope you can join!

The fix is actually pretty easy, but its too late to get it into E-3, so I
will commit it for E-4.

Dan
