1.9.0 rmilter.conf.local parsing errors

[basbebe]

in my rmilter.conf.local, this gave me parsing errors:

redis {
[…]
copy_probability = 0.5;
[…]

config file </usr/local/etc/rmilter.conf.local> parse error! line: 128, text: "0.5", reason: syntax error

this also gave errors:

redis {
[…]
dbname = 3;
[…]

config file </usr/local/etc/rmilter.conf.local> parse error! line: 167, text: 3, reason: syntax error

In the last case, it was possible to use dbname = "3"; (though I haven't checked if it is working correctly yet).

In the first case I couldn't find the error / a solution…
