Actually, it was the D sting this time. Tokai Gakki Model 51 Fransican classical. Last couple of sets were Martin Silk and Steel, and some Flamenco strings I can't remember. This last set has only been on for a month or so. Went to serenade my wife for her birthday, opened the case and the D is just hanging there like a spaghetti noodle, snapped at the bridge.
What could be causing this? I've left strings on this guitar for years and they haven't snapped or gone too far out of tune. Weather too dry here in Arizona?
Without seeing the guitar my first though is a sharp edge somewhere.

This last pack was Martin Silver-plated high-tension; great strings! I can't get a pic that details anything wrong. This has never happened before. Maybe Martin is having bad luck with their D-string winder? Nothing sharp that I can see, and I ran a file over the bridge riser to make sure.
I have to agree with the Cynic. Sharp edge. You don't mention string gauges, only ages. Strings age, even if they aren't used. I lived in Denver for 15 yrs and I could see the strings start to rot as soon as I put them on the guitar.
Where did the string break? Nut or bridge? I'm guessing at the nut. A thin file or even an emery board could widen the string slot and eliminate the tight spot. I've also used a feeler guage and some #400 wet/dry sandpaper.
Just don't gouge the nut and change the angle of the slot.
