Kernel Version: 6.14.5-arch1-1 (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 5700U with Radeon Graphics
Memory: 15,0 GiB of RAM
Graphics Processor: AMD Radeon Graphics

kmail2 in version 6.4.0 (25.04.0)

B) How to reproduce (?) the behaviour reported in this bug report (i. e. what I did before the behaviour started to appear):

1. Start Kontact
2. Activate among other things the "Akonadi Database Manager" (?) option in KMail Settings > Plugins
3. Try to restart Kontact or KMail: All attempts fail, i. e. within the current KDE session, after a re-login into KDE and also after a reboot:

<Unprivileged User>@<Hostname>:~$ kontact
org.kde.pim.pimcommonactivities: Plasma activities is not running:  1
*** KMail got signal 11 (Exiting)
*** Dead letters dumped.
KCrash: Application 'kontact' crashing... crashRecursionCounter = 2
Segmentation fault (core dumped)
<Unprivileged User>@<Hostname>:~$

<Unprivileged User>@<Hostname>:~$ kmail
org.kde.pim.pimcommonactivities: Plasma activities is not running:  1
*** KMail got signal 11 (Exiting)
*** Dead letters dumped.
KCrash: Application 'kmail' crashing... crashRecursionCounter = 2
Segmentation fault (core dumped)
<Unprivileged User>@<Hostname>:~$

C) Corresponding output of "journalctl -b -r" about this behaviour:

to f. e.:

~/.config/pimpluginsrc_DEACTIVATED
