Gluster users - Sep 2013 - Adding and removing a brick from a replicated volume breaks volume geometry

As reported over here: https://bugzilla.redhat.com/show_bug.cgi?id=1002556

tl;dr:

1. Have a replicated volume (tested on 3.3 and 3.4)
2. Add a brick
3. Remove that brick
4. Restart gluster
5. Volume is slightly broken

Just using simple adding and removing, we end up with a broken volume that
behaves pretty non-deterministic.
We're trying to get the setup automated, so this is pretty much a blocker
for us :(

Has anybody else seen this behaviour?
