Thanks for the report.

Is this with the default /etc/chrony.conf or did you make any modifications?

Thanks, I can reproduce it now. It may happen when some sources have the prefer option.
Comment 14 Miroslav Lichvar 2014-04-09 15:00:14 UTC 
This is fixed in upstream git and will be in chrony-1.30.
