Google Calendar reminders display unnecessarily

After waiting for hours and several reboots later, I am still seeing all my old Google Calendar reminders. I disabled all the calendars in Online Account and verified that they were not in Evolution any longer. Upon reboot I am still seeing endless reminders for my Google Calendar which I can guess from top (they are chewing CPU) are from libnotify-osd.

As much fun as it is re-living the events from the last couple of years, it is somewhat annoying and chews GPU moderately enough with the fade in/out to slow down things in a noticeable way.

So I killed libnotify-osd which gives me a two second break, after which it respawns and the messages/reminders are back. I really have no idea how to stop these things. It may be worth noting I had google accounts (that I removed) already configured in evolution during the upgrade and I have switched to using the Online Accounts interface.

After I completely removed all the Online Accounts and rebooted my reminders went away. I then re-added just one online account and only enabled Calendar... and a stream of old calendar reminders is spamming me again. I guess I'll leave this on overnight and see if it actually stops.

I just upgraded to the 3.1.92 backend which fixes the link between the Birthday Calendar and Contacts (https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/853905) and now I am being reminded about every birthday I have in my calendar (from contacts), old or new.

I'm not sure if it is related, but I also see about 76 of these in my .xsession-errors

(evolution-alarm-notify:2442): evolution-alarm-notify-WARNING **: Could not send notification to daemon
(evolution-alarm-notify:2442): evolution-alarm-notify-WARNING **: alarm.c:260: Requested removal of nonexistent alarm!

This patch against current 3.2.0-0ubuntu2 resolves the duplication of reminders.

hmm.. says released as of 9-30, but today i don't see anything newer that 3.2.0-0ubuntu2 that still requires manual patching

Thank you for your work, the fix will be in 3.2.1 which will be a stable update for Oneiric

The fix worked for me.

The same issue described here is present on Ubuntu 15.04 with the out-of-the-box evolution 3.12.11, with slightly different steps to trigger it:

1. Opened Evolution
2. Switched to Calendar view
3. Right-clicked in the calendar list and chose "New Calendar"
4. Selected "On The Web"
5. Provided an iCalendar URL (from a Google Calendar with 1+ year of events)
6. Cleared the "user" field
7. Clicked "OK"

OSD notifications were immediately enqueued for seemingly all of the calendar's past events, starting with the oldest, which were all displayed one-by-one.

Two things wrong here:

1. There is no useful reason to trigger a notification for a past event (*maybe* events in the last hour would be relevant).
2. Events fetched from a remote calendar during an initial download should probably be exempt from various triggers/hooks that cause things like notifications and reminders to be processed. This might be moot if the previous point is addressed.
