632981 - unreckognized timezone stops calendar loading

Status: RESOLVED DUPLICATE of bug 632352

(Calendar :: General, defect)

Description

[Miquel van Smoorenburg]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_6; en-us) AppleWebKit/533.19.4 (KHTML, like Gecko) Version/5.0.3 Safari/533.19.4

I added a new caldav calendar, but I only saw 2 events in the calendar while I know I have lots. I can add events from within lightning, but they do not show up in lighting. I can see them in iCal, though.

It turns out that (at least) one calendar entry from the caldav calendar has an unreckognized timezone, and when trying to warn about that lightning dies. Commenting out the warning part from the code makes it all work again.

Reproducible: Always

Steps to Reproduce:
1. Add caldav calendar with entries with unreckognized timezone

Actual Results:  
Calendar shows up partially

Expected Results:  
Should see all entries in calendar

(full error is lower down)

Comment 2

[PM]

I also reproduced the problem with the event described.
the problem seems to be a problem in timezone DTSTART and DTEND.
i think Lightning can not process DTSTART and DTEND correctly because component TIMEZONE is needed in this case.
