Summary: Kalendar crashes after saving an all-day event
Classification: Applications
Product: kalendar
Version: unspecified
Platform: Archlinux
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: claudio.cam...@kde.org
Reporter: st.ja...@web.de
CC: c...@carlschwan.eu
Target Milestone: ---
Application: kalendar (23.04.0)
Qt Version: 5.15.9
Frameworks Version: 5.105.0
Operating System: Linux 6.2.12-arch1-1 x86_64
Windowing System: X11
Distribution: Arch Linux
DrKonqi: 5.27.4 [KCrashBackend]
-- Information about the crash:
Creating a new all-day event in Kalendar, saving it, reopening it, and saving
it again causes Kalendar to crash.
I am using a calendar from my self-hosted Nextcloud instance.
The crash can be reproduced every time.
-- Backtrace:
Application: Kalendar (kalendar), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized
