I remember having a similar problem in the one Genie program I've written so far.
I don't have an exact solution, but found this worked for an array of strings:

class log_hit : Object
    _fields : array of string[]
    prop readonly ip_address : string
        get
            return _fields[1]
    construct ( )
        _fields = new array of string[10]

I found using the _variable_name overcame what is probably a memory corruption bug 
when I used prop private. Then creating the actual array when the object is constructed
works for an array of strings.

So you could try something along the lines of:
class my_class : Object
    _channel_map : dict of string, Gst.ChannelPosition
    construct()
        _channel_map = new dict of string, Gst.ChannelPosition

If this inspires you to find a solution let us know!
