Bizarre - this seems to be a python 2.4 only property... and is also 
odd in that python is trying to convert ssidref to an int (rather than
an unsigned one). Possibly a side effect of the unified int/long stuff, 
possibly a minor change in the native method interface, possibly a 
change to u32.py...

Well not really a fix so much as a "make the exception go away" :-) 
I'll take a look tomorrow at the best way to fix this - may be that
Keir's suggestion of using 0 as the 'null' ssidref is correct, although
zero currently has another meaning... 

cheers,

S.
