Description jolay 2011-05-03 00:31:26 UTC

Application: akonadi_ical_resource (0.1)
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.6-0.5-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

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

Primary bug: I move task without associated hour by dragging it with mouse from one day to the other in the kontact task panel (korganizer top panel) and akonadiserver crashes most of the time.

Other noticeable bug is that doing the same operation may associate the task with hour set at 0:00 (midnight) when akonadi does not crash. The task positionned at midnight is out of normal view and the user may think it has disappeared!

Dragging task from top panel (task without associated hour) to the calendar panel ( task with associated hour) fails sometimes: the task reverts to the top panel automagically  (without associated hour) as for late tasks (red).

I am not sure it has something to do with other reported bugs (task modification/deleted).
My personnal calendar is stored in a local ics file mixing events and tasks.

reproducible many time: I cannot identify the exact condition. Maybe mouse operations with late tasks. htop shows many processes racing for cpu usage (5-7 PID at 35%CPU each) notably korgac, kontact and nepomuk/virtuoso/mysqld or akonadi, xorg etc before crash.

- Unusual behavior I noticed:

The laptop is running very slowly, 
most of the time I have cpu usage at 100% (dual core),
I have to wait  ~ 5 to 10 mn of 100% CPU usage after KDE4 login (user autostart launch yakuake)

sysinfo:
NVIDIA 270.41.06
laptop dell precision m65

Best regards,

The crash can be reproduced every time.

- What I was doing when the application crashed:
same thing: move Todo in kontact weekly view -> akonadi crash
nvidia driver is the one from Nvidia (not the nouveau driver)

I do not know if it is informative since it took time to capture the top result
