Looks right. Just to be sure there are no other wiring problems interfering with the i2c, connect only VCC, Gnd, SCL and SDA.
If it still won't scan, contact support@adafruit.com with a link to this thread for a replacement.

What is the extra IC on your breadboard?
I see that your 5V source is connected to the left side of the breadboard rail, and you are powering the servo driver from the right side of the breadboard rail. Some breadboards have a split between the left and right sides of the power rails - make sure you actually have power on the leads going to the breakout.
