Yes I did. In Bulgaria I met a dutch cyclist who broke his fork and had to travel over a 1000km with a fork fixed up with some pieces of wood. Heinz Stuck of course can tell you a lot about broken frame as his frame broke dozen and dozen of times. I remember him telling me that it now is hard to find any junction of his frame that never had been welded! Of course he biked for about 45 years and over 600,000km but it still tells you that it does happen. I met another guy in Thailand who told me that he broke his aluminum frame in the middle of nowhere and that he will never travel on an aluminum bike ever again. I heard a few other similar stories but those one are from people that I actually met. Beside the fact that it is easier to weld, I think that the best advantage of steel is the comfort, I found that a loaded steel bike is much more comfortable to ride as it is much less stiff.
