Bug 286139

Version:           1.6.0 (using KDE 4.7.3) 
OS:                Linux

With korganizer / Akonadi syncing against a locally running Zarafa iCal server (CalDAV resource), the earliest entry shown in this calendar by korganizer is duplicated. After removing one of the two equal entries, it reappears again. If both are deleted in korganizer, the second earliest entry (= new earliest entry) is duplicated (at least as soon as a new later entry is created).

By using AkonadiConsole's Browser, one can see that the respective entry appears twice: Once correctly with remote ID "http://127.0.0.1:8080/caldav/<username>/<UID of the VEVENT>" and once just as "http://127.0.0.1:8080/caldav/<username>", e.g., without any UID. (Zarafa is running locally and listening on port 8080.)

If I understand this correctly, the second entry should not be present.

Reproducible: Always

Steps to Reproduce:
- Setup CalDAV Server.
- Within korganizer, connect to CalDAV Server.
- Within korganizer, create several events and wait for the sync to happen.

Actual Results:  
The earliest entry in the newly created calendar in korganizer appears twice.

Expected Results:  
It should just appear once. Due to the above observation with the presumably wrong remote ID, the event can only be removed from within korganizer.

The CalDAV server correctly just shows one earliest entry.
