addons: smbd crashing with email address as Windows username

The problem

In Windows 10, navigating to \homeassistant.local\ crashes smdb when the Windows username is an email address. On a new Windows 10 build, without a prior samba login, the current username is sent for authentication and crashes smdb before I can be prompted for the configured username and password.

Environment

• Add-on with the issue: samba share
• Add-on release with the issue: 9.5.0
• Last working add-on release (if known):
