Description Niko Böckerman 2011-05-12 19:32:53 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.36-tuxonice-r3 x86_64
Distribution: "Gentoo Base System release 2.0.2"

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

Every time I login and the desktop is shown, few seconds passes and then plasma desktop crashes and restarts. This happens every time.

I have deleted all calendars from Akonadi, only Birthdays & Anniversaries remaining along with some Contacts.

Version of kdepim components: 4.4.11.1

I don't know what other information would be helpful but I am willing give more information when requested. Hopefully this gets fixed soon as I'm starting to hate those crashes every time I log in.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault

Comment 1 squan 2011-05-13 21:24:45 UTC 
I'm following openSUSE factory quite closely (tumbleweed, kde:factory, kde:unstable_factory repos) and had crashing both plasma-dasktop and kwin on login for the last two days (reproducable and on more then one user account).
For kwin it was possible to workaround since it did not crash when restarted from within the session. plasma kept on crashing (but I did not record a backtrace).

Another update of 37 new packages today fixed plasma (could be restarted even w/o leaving KDE session).
Thes packages were oxygen-gtk, many NetworkManager packages no akonadi and many unsuspicious multimedia packages.
Comment 2 squan 2011-05-14 08:59:26 UTC 
Pardon, the crash in comment #1 seems to be unrelated to the original report and maybe related to using bleeding edge plasmoid-networkmanagement 0.9.1.
