<!--
Kamailio Project uses GitHub Issues only for bugs in the code or feature
requests. Please use this template only for bug reports.
If you have questions about using Kamailio or related to its configuration
file, ask on sr-users mailing list:
*
https://lists.kamailio.org/mailman3/postorius/lists/sr-users.lists.kamailio.org/
If you have questions about developing extensions to Kamailio or its existing C
code, ask on sr-dev mailing list:
*
https://lists.kamailio.org/mailman3/postorius/lists/sr-dev.lists.kamailio.org/
Please try to fill this template as much as possible for any issue. It helps
the developers to troubleshoot the issue.
Note that an issue report may be closed automatically after about 2 months
if there is no interest from developers or community users on pursuing it, being
considered expired. In such case, it can be reopened by writing a comment that
includes
the token `/notexpired`. About two weeks before considered expired, the issue is
marked with the label `stale`, trying to notify the submitter and everyone else
that might be interested in it. To remove the label `stale`, write a comment
that
includes the token `/notstale`. Also, any comment postpone the `expire`
timeline,
being considered that there is interest in pursuing the issue.
If there is no content to be filled in a section, the entire section can be
removed.
You can delete the comments from the template sections when filling.
You can delete next line and everything above before submitting (it is a
comment).

### Description
Kamailio segfaults on startup. After a bit of digging, it looks like the issue
is caused by trying to publish something related to an expired dalog which is
present in the database:

### Troubleshooting
#### Debugging Data
<!--
If you got a core dump, use gdb to extract troubleshooting data - full
backtrace,
local variables and the list of the code at the issue location.
gdb /path/to/kamailio /path/to/corefile
bt full
info locals
list
If you are familiar with gdb, feel free to attach more of what you consider to
be relevant.
