I think I have found what causes this, and it would be good if someone 
could confirm.

If an individual map has more than 16 regions then the transfer fails 
for that file.  It doesn't appear to make any difference if there are 
other maps selected or not.  I modified mkgmap to limit to 16 regions 
per file, and have a complete map of Germany that appears to work.

I think this is more that we don't know how, rather than not possible, 
but I don't have any ideas on what can be done to fix it at the moment.
