Sentry Crash Report:

Description heikki 2014-08-20 09:08:08 UTC 
Application: akonadi_kcal_resource (4.13)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.14-2-amd64 x86_64
Distribution: Debian GNU/Linux testing (jessie)

-- Information about the crash:
Occasionally the crash report pops up, complaining about a SEGV, as in the stack trace below. The trace doesn't look very useful otherwise.

I have three calendars defined in KOrganizer, one disabled, two enabled. The two others are work-related google calendars, and Locatelli-H is my own personal calendar, on a sftp: server (locatelli, my home server). 

For some reason I can not get to the calendar properties of that calendar, although the others work just fine, so I can not see the exact address or refresh timing.

The crash repeats every half hour or so, probably related to the refresh frequency. It can not be provoked by manually refreshing the calendar.

These crashes started to happen when I upgraded to Debian/Jessie yesterday.


-- Backtrace:
Application: Locatelli-H of type KDE Calendar (traditional) (akonadi_kcal_resource), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Comment 1 Simon Reed 2014-12-23 15:39:34 UTC 
I think this is related, rather than a new bug.  I cannot post this using the automated method because of the "error code 410" on bugzilla.


Application: akonadi_kcal_resource (4.13)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-43-generic x86_64
Distribution: Ubuntu 14.04.1 LTS

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

I am trying to get KOrganizer or Zanshin to read my previous KOrganizer data.  I tried adding a 'KDE Calender (Traditional)' resource in the KDE Settings and got this crash.

Comment 2 Denis Kurz 2016-09-24 20:45:43 UTC 
This bug has only been reported for versions older than KDEPIM 4.14 (at most akonadi-1.3). Can anyone tell if this bug still present?

If noone confirms this bug for a recent version of akonadi (part of KDE Applications 15.08 or later), it gets closed in about three months.
Comment 3 Denis Kurz 2017-01-07 21:40:54 UTC 
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
