Application: kded4 ($Id$)
KDE Platform Version: 4.9.2
Qt Version: 4.8.2
Operating System: Linux 3.4.4-030404-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Just starting system, crashed apparently after entering kwallet password.
There was already started:
skype
ubuntu one
spideroark
dropbox
insync (for gdrive)
dolphin
tomboy

There are countless similar reports but I can not figure out if they refer to my version of plasma or not because I do not know how to get the version.

For sure it isn't the first time I get the problem and my SO is fully update.

I'm on a laptop (acer tm 8471) with 8 Gb Ram and kubuntu 12.04

The crash can be reproduced some of the time.
