if AffymetrixCelSet is from aroma.affymetrix, then the line above results in

 > setOldClass(AffymetrixCelSet)
Error in x[length(x):1L] : object of type 'closure' is not subsettable

maybe you meant

setOldClass("AffymetrixCelSet")

but if I put that in a package that either Depends: or not on 
aroma.affymetrix then I don't see the warning in your original report. 
I'm not sure you've diagnosed the problem correctly?
