only time i've seen a side seal break is due to an imbalance in the engine such as S4 rotor housing mixed with a S5 or 2 different compression rotors. it usually happens when half the motor is carrying the other half.
i would guess detonation could cause a side seal to break but it doesn't seem to be very common, usually the apex seals go first.
the last cause is poor porting, but it doesn't appear that the side seal caught the edge of a port by the looks of it but check your irons and make sure the edges are chamfered on the closing edges and not ported too far out towards the intake runner.
