   Resolution: Fixed
 Reviewer: Joel Knighton
Fix Version/s: 4.0
   3.11.1
   3.0.15
   Status: Resolved  (was: Ready to Commit)

Thanks Joel.

Committed to 3.0 as {{67ac1496cc9e7d9d15be28b9536e9cdbce42473d}} and merged to 
3.11 and trunk WITHOUT adding CHANGES.txt entry, because it's just a test fix 
and never hit a release (not quite a ninja).
