Created attachment 137428 [details] The problematic events don't have the same naming pattern Sometime, when I create an event in Korganizer, it is not synchronized with my Google Calendar (that uses CalDAV, isn't?). Even if I try to refresh the calendar manually, it does not appear on Google web interface. I have launched akonadikonsole. I have been able to detect the guilty events easily, they don't have the same ID pattern (see screenshot) than the others and they don't contains the field: "X-KDE-LIBKGAPI-EventId". I have tried to modify the subject of the event, but it does not fix the problem. Then I have tried to cut then paste the even. This time, it has worked. I think that the problem exist for a while but I didn't take time to look at it closer before. This issue is probably related to #325485.

I have just noticed that it is easy to reproduce the problem by creating an event while not connected to internet (as in #325485).
