I once did something similar--except it was with one of those cup-a-soups. I put it in for 3 minutes instead of the required 30 seconds. I caused the microwave to burn itself out. I had to contribute for a new one (this was at work).
I think somebody was putting one over on you. The only way I can think of you might damage a microwave, other than putting metal objects in it, might be running it with nothing in it at all, and I'm not sure that would actually hurt it. It's just bouncing electrons creating friction as they ricochet through things. The oven is shielded to prevent them from escaping the box.
skibum, I doubt you did anything that would have hurt the oven or caused it to catch fire, unless the popcorn bag had burst into flame (which it may have), and that would still be inside a metal box, so it shouldn't start a house fire. It may smell like charred ash for a while.
Funny thing is, a lot of microwave popcorn stinks so bad while it's popping (from the blends of flavorings they soak it in), that it could be smoldering for several minutes and you might not notice. Somebody I worked with years ago loved a particular flavor that smelled like dirty diapers. It tasted fine, but it sure stunk up the kitchen and the hallways.
