[BioC] GC-RMA on m430a chips

I have been able to perfom gc-rma on the mu74av2 chips with v0.4 of 
gc-rma.

When I tried using gc-rma on the m430a chip I got this error:

 >stu.gcrma<-gcrma(stu.ab)
 >Loading required package: moe430aprobe
 >Loading required package: matchprobes

 >background correction: gcrma
 >normalization: quantiles
 >PM/MM correction : pmonly
 >expression values: medianpolish
 >background correcting...done.
 >normalizing...Error in as.vector(data) : NA/NaN/Inf in foreign 
function call (arg 1)

I was able to perform regular rma on the same affy batch object 
(stu.ab), so I don't think there is a problem with the ab object.


Any suggestions?
