            Bug ID: 279810
           Summary: Owntone crashes when selecting an airplay target
           Product: Ports & Packages
           Version: Latest
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)
          Assignee: ports-bugs@FreeBSD.org
          Reporter: adorno-cabezal0j@icloud.com

I installed Owntone's last version and it detects all the possible targets,
including Airplay ones.

When selecting the Airplay target, though, it exits on SIGSEV

```
* thread #16, name = 'player', stop reason = signal SIGSEGV: invalid address
(fault address: 0x16c)
    frame #0: 0x00000000002b2bed owntone`___lldb_unnamed_symbol2066 + 77

The web hook cannot be established at this point because the service is down.

This is my configuration at the moment:

# A quick guide to configuring OwnTone:
#
# For regular use, the most important setting to configure is "directories",
# which should be the location of your media. Whatever user you have set as
# "uid" must have read access to this location. If the location is a network
# mount, please see the README.

# In all likelihood, that's all you need to do!

Please, let me know how can I assist you to debug the issue or understand the
