I _think_ that this can be reproduced outside sunbird, but I haven't got 
time to try right now. I hope to work on a reduced testcase some time 
soonish.
But for now I can give instructions on how you can get the call to 
.insertBefore triggered in sunbird:
- build and start sunbird
- switch to month view (menu: view -> month view, or the toolbarbutton)
- add an event (file -> new event, or double click on any day box)
- Save the event (button save and close)

The item should be in the view now, and thus call .insertBefore. The 
call to that is here:
http://bonsai.mozilla.org/cvsblame.cgi?file=/mozilla/calendar/base/content/calendar-month-view.xml&rev=1.103&root=/cvsroot&mark=534#498

If you want to re-trigger this call, you have to switch to a different 
month, and then switch back:
- use the forward navigation arrow just above the month view to switch 
to the next month
- Use the backward arrow to move back
