Hi,
backtrace please.
Thanks
Comment 2 Robby Engelmann 2023-12-12 07:03:49 UTC 
BTW, there is also no pop3 working, but the ews ressource did its job
Comment 3 Robby Engelmann 2023-12-12 07:04:52 UTC 
this is what shows up in konsole:

Comment 5 Robby Engelmann 2023-12-12 09:44:41 UTC 
does this:
>qt.dbus.integration: Could not connect "org.freedesktop.NetworkManager" to "stateChanged" : Type not registered with QtDBus in parameter list: QNetworkManagerInterface::NMState
>qt.dbus.integration: Could not connect "org.freedesktop.NetworkManager" to "connectivityChanged" : Type not registered with QtDBus in parameter list: QNetworkManagerInterface::NMConnectivityState

hint, that kmail is not able to establish a network connection and this is why no mails can be pop'ed and the sending fails.
And the failed sending triggers a crash?
And the ews ressource works because making use of another connection protocol?
...I am only wildly guessing...
Comment 6 Luca Beltrame 2023-12-14 10:41:06 UTC 
The EWS resource fails for me in the same manner, for the record. The backtrace lacks some debug symbols, here's a more complete one:

Comment 7 Robby Engelmann 2023-12-14 11:40:40 UTC 
This is right, the EWS fails here as well in terms of sending.
Comment 8 Luca Beltrame 2023-12-15 06:54:08 UTC 
I wonder if it's related to 72af8c0b4b20813983a0ee0384ac248e097c4a21. I'll check...
Comment 9 Luca Beltrame 2023-12-15 07:14:06 UTC 
I reverted the change and then reinstalled Akonadi. It did not crash, but it did not crash also when I went back again to master...

@Robby: Can you try issuing "akonadictl fsck" and see whether this changes anything?
Comment 10 Robby Engelmann 2023-12-15 07:55:27 UTC 
akonadictl fsck did not help here,
nor directly try to send nor after a restart.
still crashing.

BTW, this bug started with the same timing:

No these warnings were harmless and are now fixed in https://codereview.qt-project.org/c/qt/qtbase/+/527739.
Comment 12 Robby Engelmann 2023-12-29 13:54:42 UTC 
Works in recent git master snapshots (for over one week)
