kactivitymanagerd coredump info
SUMMARY
The activity manager daemon crashed during startup after I have logged out from
my system and logged in again. This does typically not happen and is not
reproducible deterministically. But it could have something to do with the
waiting time between log out and log in, which was quite short in the case of
this reported crash.
I can see the following logs in my systemd journal:
Apr 04 09:08:37 maybach kactivitymanagerd[7416]:

initialized. Reinstalling the application may fix this problem.

Failed to start Xdg Desktop Portal For KDE.
Apr 04 09:08:37 maybach systemd-coredump[7470]:
[🡕] Process 7442 (xdg-desktop-por) of user 1026 dumped core.
See the attached core dump.
I could also provide a core dump for xdg-desktop-portal-kde, but it looks
almost the same as for kactivitymanagerd. Therefore I did not attach it yet.
EXPECTED RESULT
I can imagine that this is just a follow-up error from an incomplete startup
process. As the systemd journal log says, the "Qt platform plugin could [not]
be initialized". But I guess at least the activity manager daemon should handle
this situation without a crash.
