Invalid bridge configuration

I have a default installation mosquitto version 1.2.3 running in Windows 8 as a Service.
Now when i add the following bridge configuration to my mosquitto.conf:

connection test
address someaddress:1883
topic # both "" 673312f75fe6/

and restart the service i get the following error:

Error: Invalid bridge configuration.
Error found at mosquitto.conf:566.
Error: Unable to open configuration file.

I've try'ed to narrow everything down by only setting the address and no bridge or only the connection name but i keep getting this error ... what am i missing here ? this must be something very stupid :(

Please help me i'm desperate!
