Bug 491750

Application: akonadi_ews_resource (5.22.3 (22.12.3))

Qt Version: 5.15.10
Frameworks Version: 5.115.0
Operating System: Linux 6.10.3-amd64 x86_64
Windowing System: X11
Distribution: Debian GNU/Linux trixie/sid
DrKonqi: 5.27.11 [KCrashBackend]

-- Information about the crash:
Whenever kmail (akonadi) downloads emails from my Microsoft account, the EWS mail agent crashes.

Looking at log messages from akonadi (akonadictl start --verbose) this seems to be because of a problem when reading certain calendar items. It does not happen for all items, but since some "bad" items are somewhere in my account, I cannot read email anymore without restarting akonadi (or at least the agent) each time.

The problem has started some weeks ago, probably after a software upgrade on my part, but I do not recall when exactly, nor what version I had before. I'm using now:
libical3    3.0.17-1
kdepim-runtime   4:22.12.3-2+b1

[Note: Unfortunetely there's now way to configure the EWS agent to only get emails, but not calendar entries, which I don't really need. Eeven with server side subscription enabled, and unticking the "Calendar" directory, the EWS agent still fetches calendar items, and then crashes.]

The message (including the bad string) I get from the logs is this (I've replaced sensitive names and emails with "abcdefghij.."):
