I'd say for now at least the fix would be to alter get_nse() to fall 
back to ''. You don't want the work-around code duplicated in multiple 
places. Indeed, the normal blast parser should be altered to return 
undef as well.

Then if a more desirable solution is thought of in the future, there's 
just one place to implement it: in get_nse().
