Thanks a lot.
OK I pushed out two new tags
test1 with just the cleanup reverts
test2 with a bugfix in this area
I would very much appreciate your testing report on both -
should be ok but better make sure.
Unfortunately it's past 2am here so I don't have the time to
test - and I'm at a conference so not a lot of time during
the day either.
Christoph, I still think your cleanups were a good idea,
but we need get this release into a stable shape ASAP.
Let's try again for the next release, OK?
