Ehrm, no, that line does *not* have to be added. Instead, as I assumed, 
your port is broken: 0 is of course not a valid size but a hint that 
this is the default config option and that the size is port-dependent. 
Your port should either handle this (and replace 0 by default size) or 
assert (or throw or whatever is needed to tell the developer that this 
doesn't work).

Nice to see this was the only problem though :-)
