Description Thomas Tanghus 2011-08-01 22:21:26 UTC

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I wasn't really doing anything related. 
Programs open:
Google Chrome
Kontact
Konsole
Amarok

Had 3 crashes with ~1 hour. If it is Akonadi related I have 1 KDE tradition calendar in remote file using memotoo.com, 1 CalDAV configured for memotoo.com, 1 CalDAV configured for Google Calendar, 1 Akonadi resource for calendar in a local file.
I have recently added the CalDAV resources for testing purposes and will try to delete them again to see if the crashes disappear. (btw: they work fine for Google Calendar but not for memotoo.com, free accounts available there ;)

The crash can be reproduced some of the time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Aborted

fwiw plasma-desktop hasn't crashed since I removed the CalDAV resources.

Comment 2 Grégory Oestreicher 2011-08-02 21:04:06 UTC

Hi Thomas,

Have you found a way to replicate this issue? Were items removed on the server before the crash? Have you deleted items locally?

Apparently the dav resource is doing something wrong, but this is going a little too far in Akonadi's internals to diagnose by just looking at a BT (at least for me), so I'd like to replicate this to debug.

Cheers,
Grégory

Nothing should have happened serverside. I might have added event(s) to KOrganizer which would then have been synced to memotoo.com via the traditional Calendar in remote file resource. BTW: the two CalDAV resources where disabled (not checked in KOrganizer) when the crashes occurred.

As it took a while (several logins/reboots) for the crash to appear it might take a while to see if I can reproduce it. 

I'll add the CalDAV resources one by one and wait to see what happens :-)

New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.7.00 (4.7.0) using Qt 4.7.2

- What I was doing when the application crashed:

I was away from the box but had Kontact open and KMail would have checked for mail during that time. One thing I did change was that I had earlier today removed and readded an Akonadi IMAP ressource for Gmail because it had stopped fetching new mails.
One KAlarm was triggered but that isn't even Akonadified yet? Basically I have no idea what triggered it.

Same as last time - nothing ;-)
Sorry that I can't give any better feedback. I had Kontact running, the same resources configured. I really don't know how to reproduce it. The intervals can be 2 minutes or 2 weeks.
Now I will remove the CalDAV resources which I suppose is the reason for the crash. Feel free to suggest any other way I can give better feedback.
I haven't done any C++ programming for 15 years, but isn't it possible to catch an exception (or whatever it's called; I only do Python now) and fail a bit more graceful?

[Comment from a bug triager]
From bug 283111 (KDE SC 4.7.1): "plasma crash during google calendar refresh in kontact."
- What I was doing when the application crashed:
refreshing the calendar.  
- Custom settings of the application:
set calendar in kontact to sync with google calendar using kdepim.  
on refresh, plasma desktop crashes.  either refreshing the calendar manual or
automatic (every 5 minutes as default) will cause the crash.

I have the same problem with adding ang synchronising google calendar, plasma crashes.

Comment 11 Thomas Tanghus 2011-11-15 14:06:32 UTC

I had some crashes again using CalDAV/CardDAV resources against an ownCloud instance. Will test some more. Maybe I can get some server error logs and see if there's a pattern there.
