That library doesn't seam to be very happy on 1.0.1.
You could use the New LiquidCrystal library: https://bitbucket.org/fmalpartida/new-liquidcrystal/wiki/Home
You will need to configure the pinout for your LCD in the variable creation as indicated in the LiquidCrystal_I2C.h.
This library is compatible both for IDE 22 and IDE 1.0.1.
