Bug#985080: Akonadi server crashes because of Apparmor rules

["bs.net" <bs.net@gmx.de>]

Hi hefee,

I think I found the cause for the Apparmor messages and the crash.

The package plasma-workspace needs the virtual package default-dbus-session-
bus or dbus-session-bus.
This dependency is fulfilled by the package dbus-user-session as well as by 
dbus-x11.
On my system the package dbus-x11 was installed, which apparently triggers the 
messages or the rules of akonadi-server are aligned to dbus-user-session.
I therefore installed the package dbus-user-session and then deleted dbus-x11. 
After that all messages except one and the akonadi server crashes do not occur 
anymore. 

The only message I continue to receive is:
Mär 14 22:49:00 mcp kernel: audit: type=1400 audit(1615758540.971:29): 
apparmor="DENIED" operation="open" profile="/usr/bin/akonadiserver" name="/usr/
local/share/mime/mime.cache" pid=2305 comm=5468726561642028706F6F6C656429 
requested_mask="r" denied_mask="r" fsuid=1000 ouid=0

Maybe it should be pointed out that the Akonadi server can not be used with 
dbus-11.

Many kind regards
Sascha
