Description ermonnezza 2012-10-26 16:24:54 UTC

Application: korganizer (4.8.5)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-32-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

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

The first time, I had the Korganizer panel open, and I marked a ToDo completed.
Kontact immediately crashed, then crashed at startup every time I tried to restart it.
Also korganizer alone crashes on startup, while I can start KMail alone, so it's Korganizer that is crashing.

- Possible complications:
1.The TODO I marked completed had two subtodos, both not completed
2.The calendar file (.ics) is stored remotely (via sftp)

- What I tried already:
Reverting the task to 0% completed, both in remote file, and in local copy  /var/tmp/kdecache-myname/akonadi/akonadi_ical_resource_1
(both setting PERCENT_COMPLETED to 0% and removing STATUS:COMPLETED )
Does not help

The crash can be reproduced every time.

-- Backtrace:
Application: KOrganizer (korganizer), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Comment 1 ermonnezza 2012-10-26 16:38:28 UTC

I tried to delete the calendar, and add it again pointing to the same remote file, and it works
without problems. I then right clicked -> Use as default calendar, and it crashed again.

Also this one is reproducible. The advantage for me is that now it restarts, with the calendar not selected. So if I just use it wothout setting it as default, no problem.
If necessary I can upload a new bug report.

Comment 2 ermonnezza 2012-10-26 16:40:14 UTC

Update: it also crashes if I switch to ToDo view after the calendar is loaded

Comment 3 ermonnezza 2012-10-26 16:48:07 UTC

It also crashes if I unselect the calendar

Comment 4 Sergio Martins 2012-11-28 23:21:59 UTC

Fixed, will be in 4.11.
