Yes, well I am not entirely at home in airbag mechanics and what exactly determines whether they should deploy or not. I can imagine however, that every system has it's shortcomings and unexpected behaviour in certain (unexpected) situations, especially when the situations are as variable as during traffic. I can imagine airbags have to go by sensory data they receive from sensors measuring certain parameters (impact force, impact direction, etc). I can thus believe airbags might be able to deploy in inappropriate situations (like minor accidents) if either those sensors supply wrong data, aren't set up in a right way or any myriad of other things that can go wrong. No system has ever been perfect, but you're the expert in this field.
In any case, I personally wouldn't recommend deactivating them for the reasons you mentioned (but rather keep improving the technology). In bigger accidents they can surely be a lifesaver.
