WizFi 210 and PN532 NFC shield

I am trying to use both the shileds simultaneously

Adafruit PN532 NFC Sheild

and Wiznet WiFi shield WiZFi 210

http://www.wiznet.co.kr/Sub_Modules/en/product/Product_Detail.asp?cate1=&cate2=&cate3=&pid=1209

Both the shiels works independently

PN532 uses I2C interface
Wizfi uses SPI
the moment I include Wire.h header file
the Wizfi shield does not work and it prints junk characters in the serial

I have not connected the PN532 shield
I use only the Wizfi shield and uses one of the examples of Basic server test

without the wire.h it works
I have not changed any any line of the wizfi code but for the # include <Wire.h>
Any help

I have no experience with SPI and I2C in the same code, but WizFi 210 has UART, too. Maybe you could use it instead of SPI. I have a number of projects where I use both hardware UART, Software Serial, and I2C off a single Atmel chip, or off Arduino Mega 2560 or Pro Mini 328.
