This happens when you try to compute a root number for genus 2 curve 196.a.21952.1 at the prime 7. The pairing_matrix is expecting the indices to be clusters, but it seems that they are not clusters.

I think I've fixed this, I added a test for https://beta.lmfdb.org/Genus2Curve/Q/1503/a/4509/1 which has the same picture at 3 that the global root number is the product of the two locals also, so everything seems ok?
