If it is truly a spark ignition, you could have a grounded wiring harness.

What brand oven? Whirlpool had a big issue with this because they routed the wiring incorrectly and it would get cut by the oven frame (opening/closing oven drawer could move a loose harness and cause chaffing). Typically these ignition systems spark and open the gas valve at the same time. If you don't get ignition in 5 attempts, it stops, but you've had gas pumping into the oven cavity which can cause the odor.

Does your broiler work?

Whirlpool with a true sparker. Broiler burner at the top starts no problem. Eventually I got the problematic sparker working by fiddling with the sparker. Literally bending the housing a bit to alter the gap distance.

Nice! I did that as well when I used to repair them for a living. The spark would sometimes arc to the ignitor guard rather than the burner tube. Now, bake some cookies.
