Sorry for the mess, I'm having problems with copy-paste on firefox.

Looks like an event with a null uid is being created.

I wonder if this crash has happened to you all using KDE 4.2 or KDE 4.1.4?

All 3 backtraces are from 4.1.3

I just got this backtrace while investigating bug 180221.

It's a localdir resource problem and both dups (comment #1 and comment #2) say they're using localdir.

doc.evans, are you using a localdir resource too?

(In reply to comment #7)

It was (I am about 99% sure of this) a "Calendar in remote file" webdav resource.

From bug 219502:
---
What I was doing when the application crashed:
When adding a new event, upon choosing a WebDav calendar to which the event is
to be added, korganizer crashes.  This happens about 50% of the time.

kontact (4.4.9) on KDE Platform 4.6.00 (4.6.0) using Qt 4.7.0

- What I was doing when the application crashed:

I added a new appointment to a remote ics calendar (on a webdav resource via akonadi) using these steps:
* (Calendar open in Kontact)
* double-clicked day to add appointment to
* "New Event"-dialogue opened
* changed title
* changed end date
* clicked "ok"
* --> Kontact crashed

Happens maybe 30% to 50% of all times

Korganizer doesn't use KCal anymore, it uses KCalCore which uses QSharedPointers.

So this doesn't happen anymore.
