Assuming this instrument has becketless pins, the most likely cause is  
that the coiled wire is crossing the bit of wire that is under the  
coils, running along the length of the pin (holding the wire onto the  
pin by friction), and that this crossing is taking place on the side  
where the string leaves the pin. That creates a sharp bend in the wire  
at that point when you are tuning. To remedy, when replacing strings,  
always make sure the bottom coils don't cross that wire, by cutting  
the bottom bit of it, bending it out of the way, not making it too  
long in the first place, something along those lines.
