Description Stephan Diestelhorst 2026-01-08 11:23:57 UTC 
Application: kactivitymanagerd (6.5.4)

ApplicationNotResponding [ANR]: false
Qt Version: 6.10.1
Frameworks Version: 6.21.0
Operating System: Linux 6.14.0-37-generic x86_64
Windowing System: X11
Distribution: KDE neon User Edition
DrKonqi: 6.5.4 [CoredumpBackend]

-- Information about the crash:
I have just upgraded my KDE Neon User machine to Plasma 6.5 and after the upgrade (and reboot), kactivitymanager crashes on startup consistently and repeatedly.  Nothing obviusly wrong with the upgrade / packages, but I will have a look for similar bug reports and other inconsistencies in the system.

The crash can be reproduced every time.

-- Backtrace:
Application: kactivitymanagerd (kactivitymanagerd), signal: Aborted

Reviewing the log of the systemd unit, I see the following issue from SQLite causing this:

syon@d-allen:~$ systemctl --user status plasma-kactivitymanagerd
[...]
Jan 08 11:26:53 d-allen kactivitymanagerd[12922]: "DELETE FROM ResourceScoreCache WHERE usedActivity = COALESCE(:usedActivity, usedActivity) AND lastUpdate < :time"
Jan 08 11:26:53 d-allen kactivitymanagerd[12922]: QSqlError("779", "Unable to fetch row", "database disk image is malformed")
Jan 08 11:26:53 d-allen kactivitymanagerd[12922]: ASSERT failure in Uils::exec: "Query failed:database disk image is malformed Unable to fetch row", file ./src/service/plugins/sqlite/Utils.h, line 53
Jan 08 11:26:53 d-allen kactivitymanagerd[12922]: KCrash: Application 'kactivitymanagerd' crashing... crashRecursionCounter = 2

Moving the old database out of the way has helped (I don't use activities):
$ mv .local/share/kactivitymanagerd/resources{,.old}
