This seems to happen only for "all day" events that are set to reoccur and that have alarms.  If more than one of the reoccurring events are triggered at once, multiple copies of the event are added to the main calendar display for each day the reoccurring event was defined as the alarms are dismissed.  Note that no new events are actually created, so closing Sunbird and reopening it will fix the display.


Reproducible: Always

Steps to Reproduce:
1. create an "all day" event for a day that is several days in the past (or create one for today and wait 3 days to use Sunbird).
2. make the event reoccur every 1 day for 3 days.
3. set an alarm for 15 minutes before the event.
4. click "OK".  you should see the events at the top of the main calendar display for three consecutive days.
5. the "Calandar Alarm" window should pop up with 3 alarms (one for each of the three events you defined) since they are past.
6. dismiss each of the alarms.
7. look at the main calendar display.
Actual Results:  
Each time an alarm is dismissed, an identical event will be added to the display in the main calendar window for each day the event occurs.  for example, you will see three identical copies of the event in the above example.  If you close Sunbird and reopen it, the duplicate entries will no longer be displayed (you'll only see one as expected).


Expected Results:  
Dismissing alarms shouldn't affect the events shown in the main calendar window.
