Good question.
The obvious danger is that dry ice needs to be kept at something like - 80 C to stop the solid frozen CO2 sublimating into a gas...which of course is toxic to humans in large concentrations.
I'm reminded of an incident when a colleague was driving a van with some dry ice stored in the back - it was in several sealed bags in a normal freezer so was staying pretty frozen but enough gas must have seeped out to make the concentration in the (seperate) driver's cab dangerous as the driver came over a bit funny - lesson learned was to keep the windows open when transporting the stuff...!

It's as about as toxic as the air that is breathed out by a few passengers, or did we have in mind a cargo compartment full.
I don't like my ice cream deserts in first class to be soupy.

No, I was just reading an article on the introduction of the A340-600 with its new galley chiller system designed for lower temps. They were having problems with it and for a while were using dry ice in the galley.

We operate at a legal limit of 4 Kg of dry ice per galley, i.e. a total of 12 Kg in the passenger compartment on a B777. The limit in the cargo holds is 362 Kg. The limit varies for other aircraft types depending upon their size.

Would it make any difference where the outflow valve(s) are located? If the CO2 is ducted overboard in short order, it wouldn't make a dent in the O2 content in the cabin.
There are many worse hazards, methinks.

Don't forget that IATA DGR manual states that every passenger is allowed to bring 2 kg of dry ice as handluggage ir checked bags.
If a cargo shipper wants to send 1 kg of dry ice to cool something down - its dangerous goods. If the dry ice is used to keep food cool in the pantry it isn't, but at least the quantity is known to the airline. But each passenger can bring 2 kg.....
