One thing I have been noticing lately on a lot of bikes is that the cable housing for the front derailure gets really corroded near the derailure.
I think the upward arc of the cable encourages water and road slime to dribble down the cable into the cable housing. The housing and cable then corrode; often welding together.
This is less of a problem with high quality multi-sleeve cables, but for simple cables with a single metal casing inside and a plastic outer shell, it is common.
It would serve you well to either change your cable to the multi-sleeve type or periodically remove the cable housing and clean it with some WD-40 and an old spoke (run the spoke through the inside of the cable housing).
Spray WD-40 into the cable housing and grease your cable. This will help prevent corrosion and will provide smoother trouble-free shifting.
