Metasploit crashes on bad hosts entry

[LongWayHomie]

Steps to reproduce

How'd you do it?

1. Update msf to latest version (v6.4.0-dev)
2. Add bad host line in /etc/hosts (ex. 127.0.0.1 badhost.host. - with dot at the end)
3. Run msfconsole

Done on rolling kali release.
Here's stacktrace:

Changed only some quote marks in dump to correctly show it here. The solution is to remove this "bad" hosts entry.

Were you following a specific guide/tutorial or reading documentation?

No

Expected behavior

Metasploit Framework should start

Current behavior

Because of bad hosts entry, msf won't start

Metasploit version

Framework: 6.4.0-dev Console : 6.4.0-dev
