Hello.
I've got an install of 3.4.7 on FreeBSD which has been working properly
for years.
Recently, possibly due to some upgrades, it started crashing when a
specific user accesses a specific shared calendars.
All the users use the same client (ThunderBird 115.10) and all the users
are able to use that shared calendar except that one.
When this user's client connects to the calendar, it does not work and I
see in the logs something like:
http[24069]: login: [127.0.2.1] user1 Basic User logged in SESSIONID=<mail-1713859646-24069-1-2696860745399299929>

I tried removing and re-adding permissions for this calendar to this
specific user: nothing changed.
So I compiled Cyrus with debug info and here's the stack trace:

libical is at version 3.0.16.
Anyone else has seen this?
Any suggestion on what to try?
bye & Thanks
