I know that it does not make sense to create event when you do not have any calendar but when you have calendar tab closed you might not observe this fact and simply try to create by accident...
Have a look:

Reproducible: Always

Steps to Reproduce:
1. create new profile
2. delete Home calendar (it happens - eg. by accident)
3. double click in main view to create new event
   -> error console
Error: document.getElementById("item-calendar").selectedItem has no properties
Source File: chrome://calendar/content/calendar-event-dialog.js
Line: 543

4. Now you have two options:
  a) press OK just to check what happen if there are not calendar
     -> errro console
Error: document.getElementById("item-calendar").selectedItem has no properties
Source File: chrome://calendar/content/calendar-event-dialog.js
Line: 109

  b) press cancel to go back and create calendar
    -> if so, cursor goes into waiting mode and will not go back into default (usually arrow)
Actual Results:  
cursor = waiting mode

Expected Results:  
error console should be empty and cursor should not goes into waiting mode

it looks like Sunbird stack but I can close it and start again, what is interesting for me that after restart Home calendar is visible, do did I delete it whether not?

this is quite complicated to catch all cases when there are no calendar and user try to do something...
so mayby just disable to delete last calendar? not sure...

Additionally: After deleting the last calendar and restarting Sunbird, the calendar "Home" (location: moz-profile-calendar://) is restored, although it was not the last calendar. (Not tested with clean profile.)
