This problem exists with all Google calendars. If you create the event
in the web then it will sync OK, however, if you create the event via
Evolution then the aforementioned bug occurs. It appears you don't have
to restart Evolution for the item to appear, just exit out of the error
and refresh
Public bug reported:
Running Evolution 3.2.2 on Oneiric 64 (fully updated as of 30-3-2012)
and finding that creating Tasks or Memos impossible. When you select
the New option, you are presented with the appropriate dialog, but after
saving you are returned to the main GUI with no Task or Memo
