Entering '.' in profile "host" and/or "user" breaks restore

[DonEdwards]

For a single-user single-system environment, it makes sense to configure backintime profiles with dots in the "host" and "user" fields - skipping two levels of directories which, in this specific context, serve no function.

However, with this configuration, "restore" writes to /{profile]/{datetimestamp}/backup (copying the rest of the file path). "restore to" similarly writes to {wherever you tell it}/{profile}/{datetimestamp}/backup. {datetimestamp} in this referring to the snapshot being restored from.
