That looks odd, thanks for reporting this. I'll see if I can get to this 
on Monday, if not, it'll have to wait until after my vacation... So 
while I appreciate people running -git and finding issues like these 
before they show up in a release, might be best to revert back to 2.2.11 
until I can get this debugged.
