Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.36-gentoo-r5 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:

When using KDE (plasma-desktop, Kontact 4.6, Akonadi etc.) normally, plasma-desktop crashes on me regularly cca. every half an hour or so.

I then tried to replicate the same behaviour by shortening in Kontact/KOrganizer the time interval in which the remote iCal resources are (re)loaded to a minute and now plasma crashes every minute.

- Unusual behavior I noticed:

Just before it crashes, the Eventlist plasmoid looks like it is refreshing/redrawing. So I suspect it _may_ have something to do with that or the underlying Akonadi.

I haven't succeeded in crashing just that plasmoid in plasmoidviewer yet so far.

- Custom settings of the application:

Running apps:
 * Kontact (Summary view, KOrganizer, KMail, KJots, Akregator)
 * Konsole
 * Choqok
 * Kopete

Loaded plasmoids:
 * omni-present panels:
  + Task Timer
  + Battery Manager (stock)
  + Analogue Clock (stock)
  + Pastebin (stock)
 * everyday activity:
  + Eventlist
  + Wallpaper Clock (for background)

I have a few iCals loaded in Akonadi/Kontact. Two of which are from remote locations (e.g. webcal from FSFE) and one generated by KMyMoney.

(KDEPIM version is 4.5.96)

The crash can be reproduced every time.
