Yes, it's quite typical, and as other have noted, due to the axis of the ring not being perfectly coaxial with the axis of the bottom bracket. Also as noted above, high quality track cranks (e.g. Campagnolo or NJS-certified) will minimize the issue, but unless you're riding on a track it's not necessarily a deal breaker. The important caveat is that when you set your chain tension, be sure to check throughout the entire rotation of the crank, so the tightest point in the rotation isn't so tight that it damages your crank or hub bearings.
