Sorry, I missed that. The following example produces the error:
nmap -p 1433 127.0.0.1 --script ms-sql-info --script-args mssql.username='sa',mssql.password=''

When looking into it now, I noticed the same occurs when the argument is fetched from the registry:
nmap -p 445 127.0.0.1 --script smb-enum-shares --script-args smbuser='guest',smbpass=''

Leaving the quotes out when using an empty string or a string containing only spaces produces the same error.
Am I missing something truly obvious here?
