guam 0.9.13-1 is crashing (pykolab 0.8.23-0~kolab1)
2023-07-13 01:54:42.809 [error] <0.473.0> Supervisor {<0.473.0>,kolab_guam_listener} had child session started with kolab_guam_session:start_link(<0.473.0>, #Port<0.8>, [{host,"127.0.0.1"},{port,9993},{tls,true}], true, [{certfile,"/etc/ssl/private/cyrus-imapd.pem"}], [{filter_groupware,[]}]) at undefined exit with reason killed in context shutdown_error
Only solution I found was to downgrade to 0.9.11-1 (previous version) and then it works again.
```
# apt install guam=0.9.11-1
warning: downgrading guam from 0.9.13-1 to 0.9.11-1
