This is an interesting problem. I agree with Koop that it could be a clogged vent. As the water enters the tank, air pushes the p-trap water into the shower. Easy to test....use a plunger and go after the shower drain to get water out of the trap. Then run some water and see if you get gray tank odor out of the shower.
