I agree that it's better UI practice to disable invalid operations. It seems 
that the GtkFileChooser widget was not written with this use case in mind 
though.

I quickly tested some other programs using the GtkFileChooser (or its Dialog 
variant). None of them disables the Save As button when the Location field is 
cleared. So I think your current solution is "good enough".

This limitation does intrigue me though. If I find some time later on, I may 
try to work around it, but I can't promise.
