Force Close when viewing an Event

[AutoImport-Nutomic]

Whenever I try to open an event from caldav in the system calendar, the calendar app force closes.

DAVdroid shows the calendar as synced, and it does not matter if I create the event locally or if it comes from another device, it always crashes.

[rfc2822]

How do you create the event? This sounds like a bug in the calendar app / provider.

Please provide steps to reproduce, including your device and Android version.

[AutoImport-Nutomic]

I’m running Cyanogenmod 10.2 (so Android 4.3) nightlies. Device is Optimus 4X HD.

As I said, it happens with events that I create from the Android calendar, and with events synced from other clients (Thunderbird/Lightning in my case).

To Reproduce:
Add CalDAV account
create an event in the CalDAV calendar (from the default calendar app)
save the event
tap the event to open it

Result: The activity starts loading, but before any data is displayed, the calendar app force closes)

[rfc2822]

This is a bug in com.android.calendar/.EventInfoActivity. Even if DAVdroid would construct invalid events, these events should be denied/repaired by the calendar content provider or the calendar app. I will mark this issue as invalid because the calendar app crashes, not DAVdroid and because I can’t reproduce the problem. However, if I or you can find out what’s the exact cause of the problem, please feel free to re-open.

I tried a different calendar app from the market, and it works there without problems, so it’s definitely a problem with the Android Calendar.

One thing that is obviously null is the calendar title/name (I have no idea what it’s name is).

If you know what I mean, maybe you can send me a build where you set that to a proper value so I can test, otherwise I will see if I can find it myself.

Or you could tell me where exactly events are passed to a calendar so I can debug this myself.
