You can try to use small serial resistors (~100 to 200 ohms to the pullups) and small caps (~100pF) from SCL ans SDA to GND.

i am sorry to hear you have a "Gitch" problem.. ;P

make sure your ICs have capacitor decoupling as close as possible to the devices

although it might be a bit over-kill you might consider using a bus transeiver
