New crash information added by DrKonqi

korgac (4.6.0) on KDE Platform 4.6.3 (4.6.3) using Qt 4.7.2

- What I was doing when the application crashed:

I had Kontact and Zanshin open.

I deleted a ToDo in Zanshin and then 'korgac' crashed.

- Unusual behavior I noticed:

I suspect this crash might trigger other problems/crashes in the two applications later on (maybe related to kded4), but am not sure. Will try to notice this.

- More info on Apps:

KOrganizer is running KMail, KAddresBook, KOrganizer, KJots and AKregator

In KMail (and hence Akonadi) I have Nepomuk tags resource added.

Kontact's (and Zanshin's) resources are:
 * Kolab
 * webcal://fsfe.org/events/events.sl.ics
 * webcal://www.kiberpipa.org/sl/calendar/ical/
 * 4 local iCal files
 * 1 local iCal file, auto-generated by KMyMoney

> This should be fixed, please try 4.10

I can confirm that it seems to be working on 4.10.4 on Gentoo.

I suspect it was caused by a bug in DAV resource that got fixed in 4.10.4.
