[BioC] Differences between spikein chips and rgu34a?

Hi,

	When I read the Affymetrix HGU133 spike-in data using 
spikein<-ReadAffy() I get no problems.
 
	From a different directory, with rgu34a CEL files,
after trying chip<-ReadAffy(), I get the message 

Error in validityMethod(object) : No slot of name "phenoLabels" for this 
object of class "phenoData"	

	I never used to get this message. I have installed the 
developers versions of the software but I still get the problem. 
What is going wrong?

	Best wishes and thanks in advance,
		Harry
