Bug 279065

Application: kded4 ($Id$)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.3
Operating System: Linux 2.6.39-ARCH i686
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Just finished booting, logged in successfully, waiting for desktop top appear.  Auto load of Thunderbird and Firefox.

- Unusual behavior I noticed:
kdeinit4 crash on kwin every time, just after login, my desktop graphics effects don't start.  Pressing Shift-Alt-F12 restores the graphics effects.  System operates normally for the most part after that.  But when logging out, kdeinit4 again crashes.  Sometimes the system will log out after closing the report dialog, most times the screen goes blank except for the mouse cursor.  I can switch to a terminal and shutdown.

- Custom settings of the application:
I haven't tried this yet, I also have graphics enabled for root, going to disable that.  Perhaps theres a problem when switching from login to user session?

The crash can be reproduced every time.
