Please describe the problem:
Evolution sometimes loads all my calendar events (stored on a caldav server), but sometimes it only loads some of them. Which ones it loads or doesn't load seems to vary randomly.

Steps to reproduce:
1. Connect to a caldav calendar
2. Leave the calendar pane
3. Go back to the calendar pane


Actual results:
Sometimes all the events load, sometimes just some of them load. 

Expected results:
All the events should load every time.

Does this happen every time?
No, it happens frequently but not always. Looks like a possible race condition between evolution and evolution-data-server.

Other information:
Recurring events load in their entirety or not at all. In other words, if a recurring event loads, all of its recurrences load.
