Bug ID: 512424
Summary: KOrganizer segfaults when adding a CalDav calendar
Classification: Frameworks and Libraries
Product: Akonadi
Version First unspecified
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: DAV Resource
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: ---
Application: akonadi_davgroupware_resource (6.5.3 (25.08.3))
ApplicationNotResponding [ANR]: false
Qt Version: 6.10.0
Frameworks Version: 6.20.0
Operating System: Linux 6.17.8-arch1-1 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 6.5.2 [CoredumpBackend]
-- Information about the crash:
When attempting to add a self-hosted CalDav calendar to KOrganizer, I get a
crash report (due to a segmentation fault?) upon applying my submitted calendar
configuration. Effectively, right as the program is trying to retrieve the
calendar from the remote host, the crash occurs.
KOrganizer does not shut down during this process - I'm guessing it's spawning
a new thread to fetch the calendar, and that is what's crashing. Either way,
since the configuration panel stays open, I can reproduce the crash by clicking
the "Apply" button. The calendar is not added to KOrganizer, so I effectively
cannot use CalDav at all.
The crash can be reproduced every time.
-- Backtrace:
Application: Private (akonadi_davgroupware_resource), signal: Segmentation
