Sorry - I haven't had time to check the regtests yet, but I will either over 
the weekend or next week - apparently some mangling is going on.
It'd delay 2.16, but this problem can be fully fleshed out over a few weeks.  
Or we could just revert the patch and then re-apply a better version after 2.16 
is out.  I'll have a better sense of the size of the job after I look into it a 
bit more.
