Import an .ICS file and examine them in the week or day view and the entries look like a thick line a few pixels high but are not listed as in the month view. 

Reproducible: Always

Steps to Reproduce:
1. Import a .ICS file from WebCalendar (short version below)
2. Display month view (things look good)
3. Display week or day view and there is a thick line where the events should be but they cannot be enlarged or selected. 
4. Edit an event by selecting it from the event list and change anything.
5. Entry now displays correctly.


Actual Results:  
Events in week and day view are not visible or selectable.

Expected Results:  
Expected views of imported events to be visible in all views. 

Simple .ICS file contents:

They events have zero height because they have zero duration.
(I'm pretty sure this is a duplicate, but I don't know of which bug)

The first event has neither DTEND nor DURATION and is therefore assumed to be zero-length. The seconds event is specified to be zero-length.
