Hi Dennis--

Thank you very much for the prompt response!

unfortunately, i saw crashes several days ago when i was in the middle
of dealing with other problems and i didn't get around to doing actual
debugging until much yesterday.

Looking in my backups of ~/.local/share/linphone, it looks like
september 21 was the most recent time that linphone.db and
zrtp-secrets.db were changed.

according to my dpkg logs, i had:

2022-09-27 17:03:49 upgrade libsoci-core4.0:amd64 4.0.1-5 4.0.3-1

so maybe libsoci is the issue?

i'm using journald, so /var/log/message hasn't been touched in years on
my system, but i don't see anything suspicious in the output of
"journalctl -k --since '15 days ago'" either.

Yes, good call!  I've installed libsoci-core4.0 and libsoci-sqlite3-4.0
from bullseye, and i was able to start up linphone without an immediate
crash.

However, after restoring my configuration, and trying to place a single
call (to myself, which of course i didn't expect to work) the app
crashed again.

now, even with libsoci* from bullseye, it is crashing again at startup,
with this stderr log and backtrace:
