Bug ID: 477165
Summary: When restarted while running under systemd,
plasmashell crashes in
qDeleteAll<QList<CalendarEvents::CalendarEventsPlugin*
>::const_iterator>
Classification: Plasma
Product: plasmashell
Version: master
Platform: Other
OS: Linux
Status: REPORTED
Keywords: qt6
Severity: crash
Priority: NOR
Component: Digital Clock
Assignee: plasma-b...@kde.org
Reporter: n...@kde.org
Target Milestone: 1.0
100% reproducible for me with Plasma 6 Wayland from today's git master. Started
happening 2 or 3 days ago every time I restart plasmashell using either
`systemctl restart --user plasma-plasmashell.service` or `plasmashell
--replace`.
Of note, if plasmahell is *not* run under systemd, then `plasmashell --replace`
does not cause the crash.
Backtrace:
Thread 1 "plasmashell" received signal SIGSEGV, Segmentation fault.
