Hello Tjaart,

I've copied this reply to the configobj-develop mailing list as it 
raises an important question about ConfigObj,

Note that you didn't attach the config file, however your email has an 
important clue :

This is an 'empty value', which as far as I remember is part of the 
'ini' file spec, but not currently legal syntax for ConfigObj.

The correct way of specifying an empty value for ConfigObj is to do :

bind = ''

So it's not your inexperience - that part of the config file simply 
isn't legal syntax for ConfigObj at the moment.

Nicola (ConfigObj co-developer) - the last three support queries I've 
had for ConfigObj have all been to do with empty values. It seems that a 
lot of people are using ConfigObj to parse ini files created elsewhere.

IIRC the empty value *is* part of the normal ini spec. (A later version 
of ConfigObj 3 supported them.) Would you object to me extending 
ConfigObj to read empty values ?

A logical counterpart to this is an additional option (default False) 
allowing you to specify that ConfigObj should write out empty values in 
place of the empty string.

What do you think ?

All the best,
