           Summary: Korganizer cannot have exclusive access to Calendar
                    and crashes
           Product: korganizer
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: korganizer-devel at kde.org
        ReportedBy: stephan.diestelhorst at gmail.com


Application: korganizer (4.4.9)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.37-020637-generic x86_64
Distribution: Ubuntu 10.10

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

Trying to move an appointment in Calender view. Upon mouse release, Korganizer
complained that it couldn't gain exclusive access to the entry in a quick
dialog. After confirmation, Korganizer crashed.

This is after a system crash and subsequent reboot.  No suspicious entries in
dmesg, nothing in /var/log/messages, in particular no AppArmor craziness behind
my back.

lsof -p $(pidof korganizer) does not show the ics files being open. While
Korganizer was running, fuer -a on the calendar file showed nothing. File is on
a local FS, no NFS.

The crash can be reproduced every time.

-- Backtrace:
Application: KOrganizer (korganizer), signal: Segmentation fault
