Bug ID: 474091
Summary: KAlarm crashes when a repeated alarm runs for a long
time and other alarms are queued up behind it
Classification: Applications
Product: kalarm
Version: unspecified
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: djar...@kde.org
Reporter: gabrav...@gmail.com
Target Milestone: ---
Application: kalarm (3.5.6 (KDE Gear 23.04.3))
Qt Version: 5.15.10
Frameworks Version: 5.109.0
Operating System: Linux 6.4.12-200.fc38.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora release 38 (Thirty Eight)"
DrKonqi: 5.27.7 [KCrashBackend]
-- Information about the crash:
This crash is similar to https://bugs.kde.org/show_bug.cgi?id=468640 but seems
to be distinct.
In particular, I don't know exactly what was meant by "having an alarm
displayed" there, but I'm still getting crashes that are somewhat alike to that
bug without any KAlarm window being open from what I can see - I just have to
let an alarm run on repeat for a long time (hours, typically) while other
alarms that are supposed to run half an hour/an hour/etc. try to queue up
behind it and that seems to basically guarantee a crash within a few hours.
This frequently occurs to me (at least once a week or so) when I accidentally
leave my computer sound too low and thus don't get woken up even by the loudest
alarm I know on infinite repeat - this does mean a workaround for me would be
to just not forget to leave the sound on high but as a forgetful person I am
afraid it is unpracticable for me.
Also, I will note that I have not tested only having one repeated alarm active
to see if that still crashes, but it seems unlikely to me that the crash is
entirely because of an alarm running for a long time - or at least I'd hope
KAlarm isn't that broken at the moment.
The crash can be reproduced sometimes.
