Bug ID: 470771
Summary: Kalendar shows empty UI then crashes unless KOrganizer
is opened
Classification: Applications
Product: kalendar
Version: 23.04.1
Platform: Neon
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: claudio.cam...@kde.org
Reporter: sephiroth...@hotmail.it
CC: c...@carlschwan.eu
Target Milestone: ---
SUMMARY
It has happened to me several times that starting up Kalendar would show an
empty UI - no calendars, no events, nothing. Closing Kalendar and then opening
it again would result in a crash. I noticed that opening KOrganizer appears to
fix things: KOrganizer starts with no events shown, but in a couple of seconds
everything is back to normal; at this point it is safe to open Kalendar, which
stops crashing but shows no events as all the calendars are deselected and have
to be manually selected again.
I also noticed that, alternatively to opening KOrganizer, one can run
"akonadictl restart" for Kalendar to start working again. These two facts
together appear to indicate that there is something going on in Akonadi which
is not managed correctly in Kalendar and which therefore leads to it crashing.
It has to be noted that Kalendar is the only software to suffer from these
crashes, as all other applications and widgets that make use of Akonadi show no
issues.
It is also far from clear what the conditions are to reproduce this, as it
happens seemingly at random times.
