Description of problem:
Please, update OpenSync to a last 0.19 release. It has issued a few days ago.
Official release notes.
P.S. I've checkout libopensync today, but it is still 0.18-7.
For easier reading of the bugs involved, I would like to mark this bug as DUP
of bug #210443, which has more comments.
