For the crust, combine the bread crumbs, cheese and butter in a bowl until well blended. Press onto the bottom of a 9 or 10 inch spring form pan. Bake at 325*F for 15 minutes or until lightly browned. Cool on a wire rack.
For the filling, heat the olive oil in a large heavy skillet over medium high heat. Add the onion and bell pepper. Saute for about 2 minutes, then add the mushrooms. Saute for 10 minutes. (until liquid evaporates and mushrooms start to brown) Remove from heat and cool.
Beat the cream cheese, salt and pepper in a large bowl until fluffy. Add the eggs 1 at a time, beating well after each addition. Stir in the onion mixture, crab meat, gouda cheese and parsley. Pour into the crust.
Place on a cookie sheet and bake in the oven for 1 1/2 hours until the top is puffed and browned and the center still slightly jiggly when the pan is shaken. Cool on a wire rack. Serve warm or chilled. Store, covered in the refrigerator.
