I used to believe this argument as well. That bullpups were inherently more dangerous in the event of a catastrophic failure due to the way they are designed. So I looked into it and, maybe it's just me and my google-fu is weak, but I can't find any documented information on how much more dangerous a KB with a bullpup would be over a rifle of conventional design. Bullpups of one flavour or another have been in service with many different militaries all over the world for about 50 years, give or take. The British, Austrians, Australian, Israeli's, French etc. have all used them. And, to be sure, lots of those guns have had a lot of different problems over the years. But I believe that by now, if there was any meat to the theory that catastrophic failures in bullpups are inherently more dangerous to the shooter than catastrophic failures in conventional rifles, it would be well documented, widespread knowledge and be easy to find.
