I have a feeling that line is backwards.

It says: if the buffer has length, ignore it and use the connection, 
otherwise use the (empty) buffer data.

So perhaps this is actually a real error that is being flagged (because 
it's inlined)?

In any case, it's possible that fbConnection being null does not mean a 
null dereference, but I'd have to see the class itself. I'm surprised if 
you don't get a null dereference in non-release mode, unless this code 
is never actually called.
