we have no real chance of reproducing your problem.
you use `data' -- your "x" and "g" and "s" that we don't have
available and you use a function multicmp() which is not part of R
(which might be not called before the error though).

Typing  
      traceback()
after the error message would help potentially.

well, it's a different model you are fitting,...

maybe you could use a data frame to pass to  aov(*, data = <data frame>)
