Hi -
I'm hitting a crash in dovecot, I get this logged followed by a terse stack
trace and
systemd-coredump details not included here - full gdb stack trace and more
details are
further down:

email client is fairemail version 1.2042a on android, but an older version had
the same
problem.
I mainly use fairemail to read emails on my phone, and that is working fine but
I noticed
that deleted emails were not actually getting deleted, that it has a bunch of
"pending
operations" it has were not running, and that dovecot has been crashing like
this since
about feb 2 (over a month ago). I can't figure out what changed at that time,
but my cert
says it should have expired over a year ago, but the cert as created 26 months
ago.
log files only go back to Feb 5 so just missed that.
I generated a new cert but it's still crashing (I probably still need to do
something on
the client side or my setup is broken).
I assume there is something wrong or some "snapshot" thing that's stuck, but
since it's
crashing I can't figure out what the undelysing problem is.
Thanks for any help.
