I had his same issue with one of my classical guitars. It actually happened before I bought it, as it was a 1977 guitar. But, Charles is right. It is caused by a slight wood shrinkage and then the frets push out on the finish and separate it from the wood. The separation started at the frets and just spread a little along where the finish did not adhere to the wood quite as well. I had my luthier just take the finish off the sides of the fretboard for me and clean it up. However, that was on an old guitar with a thick ebony fretboard that already had some dings and scratches. I'm not sure how comfortable you would be doing that to this guitar! This is the only reason why a bound fretboard can be advantageous, as the tangs are cut shorter under the fret and the binding protects the finish.
The problem is that even if you keep the guitar perfectly humidified, you will still get the wood naturally moving a little bit. So, this can still happen.
Best of luck!
